Castañer E, Gallardo X, Ballesteros E et-al. Pulmonary septic emboli: diagnosis with CT. High-Resolution MDCT of Pulmonary Septic Embolism: Evaluation of the Feeding Vessel Sign, Pulmonary Tuberculosis: Up-to- Date Imaging and Management, Fleischner Society: Glossary of Terms for Thoracic Imaging, ill-defined homogeneous opacity obscuring vessels, Extention to the pleura or fissure, but not crossing it. You would not expect the apical region to be this dark, but in fact this is caused by overinflation of the lower lobe, which causes the superior segment to creep all the way up to the apical region. Non-cardiac conditions include acute aortic syndrome (e.g. Low probability: Serial CT scanning at 3, 6, 12, and 24 months, Intermediate probability: PET-CT, contrast-enhanced CT, transthoracic needle aspiration and/or transbronchial needle aspiration (TBNA), Emphysema - lucency without a visible wall. Here we have a number of x-rays with consolidation. 2009;192 (5): 1319-23. 2010;11 (6): 835-7. Here another patient with widespread pulmonary metastases of a cancer, that was located in the tongue. November 1999 Radiology,213, 553-554. by Sudhakar N. J. Pipavath1 and J. David Godwin. Interact Cardiovasc Thorac Surg. In this case the chest x-ray shows subtle findings that could be described as fine reticulation. The mucus in the dilated bronchi looks like the fingers in a glove. Atelectasis or lung-collapse is the result of loss of air in a lung or part of the lung with subsequent volume loss due to airway obstruction or compression of the lung by pleural fluid or a pneumothorax. 2014 ESC guidelines on the diagnosis and management of acute pulmonary embolism. If so, no further follow up is necessary, with the exception of pure ground-glass lesions on CT scans, which can be slower growing. Whenever you see a pleural-based lesion that looks like a lungcancer, also consider the possibility of rounded atelectasis. Wegener's is a collagen vascular disease with vasculitis involving the lung, kidney and sinuses. The illustration summarizes the findings of the different types of lobar atelectasis. 13. A way to think of the differential diagnosis is to think of the possible content of the alveoli: Another way to think of consolidation, is to look at the pattern of distribution: Now it is obvious that some diseases can have more than one pattern. Probably we are dealing with multifocal consolidations, but one might also consider the possibility of multiple ill-defined masses. A pulmonary embolism (PE) is a blood clot that develops in a blood vessel elsewhere in the body (most commonly from the leg), travels to an artery in the lung, and forms an occlusion (blockage) of the artery. The consolidation is a result of lunginfarction and bleeding into the alveoli. The article shows that ventilation-perfusion ratio (/) scanning can be an alternative for the study of acute pulmonary embolism (APE). American journal of roentgenology. Discover (and save!) Interventional radiology in the treatment of pulmonary embolism. However if this patient had weight loss or long standing symptoms, we would include the list of causes of chronic consolidation. Clinical presentation of patients with PE typically includes dyspnea, chest pain (particularly pleuritic or sometimes dull), or cough; however, clinical presentation can range from being asymptomatic to sudden death, and urgent diagnosis is critical. 2007). The radiographic features of acute pulmonary thromboembolism are insensitive and nonspecific. Management decisions in patients with submissive PE remain complicated due to incomplete … Thrombotic complications in patients diagnosed with coronavirus disease 2019 (COVID-19) are emerging as important sequelae that contribute to significant morbidity and mortality (1,2).Pulmonary embolism (PE), deep vein thrombosis, ischemic stroke, and myocardial infarction are examples of complications described in patients with increasing frequency (1,2). The disease started as a persitent consolidation in the left lung and finally spread to the right lung. The characteristic finding is a hyperlucent area of the lung surrounding a branching or nodular opacity that extends from the hilum. Notice the nodules with cavitation. This paper discusses the utility of using echo- cardiogram in diagnosing and guiding treatment in pa- tients with pulmonary embolism. Key Words: Pulmonary embolism, Massive pulmonary embolism, Venous thromboembolism, Pulmonary embolism treatment, Submassive pulmonary embolism, Catheter directed therapy, Interventional radiology Core tip: Venous thromboembolism (VTE) is an illness that is potentially life-threatening condition that affects a large percentage of the global population. First study the images, then continue reading. Here we see an old chest film, which is normal. Radiographics. Cavities can heal and end up as lungcysts and lungcysts can become infected and turn into thick walled cavities. Pulmonary embolism (PE) refers to embolic occlusion of the pulmonary arterial system. Approximately 700,000 persons per year in North America experience pulmonary embolism (PE). This problem is also seen in patients with UIP. The differential diagnosis includes chronic hypersensitivity pneumonitis, which also results in fibrosis with upper lobe predominance. The disease does not cross the fissures, but usually starts in multiple segments. Diffuse consolidation in bronchopneumonia. Apr 9, 2019 - Saddle pulmonary embolism commonly refers to a large pulmonary embolism that straddles the bifurcation of the pulmonary trunk, extending into the left and right pulmonary arteries. shape. Notice the air-bronchogram (arrow). There was no eosinophilia, which excludes eosinophilic pneumonia. Parenchymal disease can present as consolidation or even as masses, but the most common presentation is a fine nodules. diagnosis of suspected pulmonary embolism; monitor pulmonary function following lung transplant; provide preoperative estimates of lung function in lung cancer patients, where pneumonectomy is planned; Technique. This is seen after radiotherapy and in chronic infection, especially TB. Here a patient with postprimary TB with cavitaty formation in the left upper lobe. Symptoms can be not specific but most manifest as a bacteremia 18with, dyspnea, chest pain, cough and other respiratory symptoms. Resolution of pulmonary embolism on CT pulmonary angiography. These are called conglomerate masses, which are the result of conglomerates of nodules. 2010;152 (7): 434-43, W142-3. Bronchoalveolar carcinoma, or now called adenocarcinoma in situ, may occasionally cavitate and sometimes present as multiple lesions. 2001 Jan; 74(877) 86-88. The left lung is almost completely compressed by the pleural fluid. Chang CH, Clayton D (1965) A Roentgen sign of Pulmonary Infarction. Radioactive seed migration to the lungs after prostate brachytherapy, Bullet emboli trapped in eustachian valve, chronic thromboembolic pulmonary hypertension, Magnetic resonance pulmonary angiography (MRPA), pulmonary embolism rule-out criteria (PERC), doi:10.7326/0003-4819-152-7-201004060-00008, the presence or absence of haemodynamic compromise, asymmetric pitting lower extremity oedema, tenderness to palpation along the deep venous system, sinus tachycardia: the most common abnormality, incomplete or complete right bundle branch block, T-wave inversion in the right precordial leads +/- the inferior leads is seen in up to 34% of patients and is associated with high pulmonary artery pressures, simultaneous T-wave inversion in lead III and V, 2-10 x increased risk, cf. American journal of roentgenology. For lesions with a benign pattern of calcification, further testing is not necessary. Gabrielli R, Vitale S, Costanzo A et-al. AJR September 2008 vol. Other things need to be considered, like acute or chronic illness, clinical data and other non-pulmonary findings. HRCT will demonstrate the random distribution unlike other diseases that have a perilymphatic or centrilobular distribution. Unlike most of the above cases, which were caused by obstruction, in this case the atelectasis is a result of compression. In many cases you can suspect UIP on the CXR. Saved by Hannah Miller. By Salynn Boyles, Contributing Writer, MedPage Today Tweaking a widely accepted strategy for assessing pulmonary embolism risk ruled out thrombosis and reduced chest imaging by a third among low-risk patients enrolled in a prospective study. Oct 23, 2017 - Explore Staley's board "Pulmonary Embolism", followed by 241 people on Pinterest. The most common cause of diffuse consolidation is pulmonary edema due to heart failure. Check for errors and try again. o Fleischner sign refers to local widening of artery by impaction of embolus (due to distension by clot / pulmonary hypertension developing secondary to peripheral embolization) British Journal of Radiology. During follow up these lesions usually do not change in configuration. For these conditions the use of double or triple-rule-out CTA could provide an alternative explanation for the symptoms. When it is idiopathic it is called cryptogenic (COP). You have to realize that it is not always possible to divide lung abnormalities into one of these four patterns, but that should not be a problem. It can be difficult to determine whether we are dealing with a reticular pattern or a cystic pattern. Fat embolism is common among trauma patients, especially those with long bone or pelvic fractures. False negatives are seen in low grade malignant tumors like carcinoid and alveolar cell carcinoma and lesions of less than 1 cm. Dec 13 2019 . Pulmonary embolism is a common and potentially fatal cardiovascular disorder that must be promptly diagnosed and treated. We will discuss them here, because the prominent feature is the lucency. The differential diagnostic list of multiple masses is very long. Magnetic resonance pulmonary angiography (MRPA) should be considered only at centres that routinely perform it well and only for patients for whom standard tests are contraindicated. This creates a reticular pattern on the chest x-ray, because the cysts in honeycombing have thick walls. No micro-organism could be isolated. Here a CXR with a reticular pattern at the lung bases. Rounded atelectasis is frequently seen in patients with a history of asbest exposure. This proved to be legionella pneumonia. In most cases of pulmonary emboli the chest x-ray is normal. Although in a necropsy study of those with lethal PE, 60% of cases developed infarction 7. [Article in English, Italian] Cotroneo AR(1), Di Stasi C, Cina A. Notice the deviation of the trachea. Previous chest radiographs should be reviewed to determine if the lesion has been stable over 2 years. Carrascosa MF, Batán AM, Novo MF. (2011) Mediterranean journal of hematology and infectious diseases. Lymphangitis carcinomatosis also produces a reticular pattern. possible obstructing mass, These findings indicate an atelectasis of the left upper lobe. Overall, there is a predilection for the lower lobes. Acute pulmonary embolism does not appear to cause dilatation of the bronchial arteries; in patients in whom the distinction between acute and chronic or recurrent pulmonary embolism at CT angiography is unclear, the presence of dilated bronchial arteries should favor the diagnosis of chronic or recurrent pulmonary embolism (, 38). High-Resolution MDCT of Pulmonary Septic Embolism: Evaluation of the Feeding Vessel Sign. diagnosis of suspected pulmonary embolism; monitor pulmonary function following lung transplant; provide preoperative estimates of lung function in lung cancer patients, where pneumonectomy is planned; Technique. Symptoms of a PE may include shortness of breath, chest pain particularly upon breathing in, and coughing up blood. On follow up films first a cyst is seen. What are the pulmonary findings? Medical Humor Nurse Humor Radiology Humor Funny Medical Medical Assistant Nursing Articles Nurse Love Baby Nurse Science. The main differential diagnosis of Kerley B lines is: Here another chest x-ray with interstitial edema and Kerley B lines in a patient with congestive heart failure. ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 1. Septic pulmonary emboli refer to the embolization of infectious particles (intravascular thrombus containing microorganisms) into the lungs via the pulmonary arterial system. Pulmonary embolism as the first manifestation of multiple myeloma. At the borders of the disease some alveoli will be involved, while others are not, thus creating ill-defined borders. Worsley DF, Alavi A, Aronchick JM et-al. There is fibrosis in the upper zones. by M. Simon Pulmonary hypertension secondary to left-sided heart disease: a cause for ventilation-perfusion mismatch mimicking pulmonary embolism. This is the most common interstitial pattern on a CXR. The image on the left also shows densities in the lung. Whenever you see an area of increased density within the lung, it must be the result of one of these four patterns. The occurrence of pulmonary emboli in 617 patients admitted to a respiratory intensive care unit was studied. These images are of a patient who had widespread bronchopneumonia and was on ventilation. Biopsy revealed the diagnosis of organizing pneumonia (OP) also known as BOOP. 7. Sharply-defined opacity obscuring vessels without air-bronchogram, Volume loss resulting in displacement of diafragm, fissures, hili or mediastinum, Mucus plug in patients on mechanical ventilation or astmathics (ABPA), obliteration of the retrosternal clear space (arrow), Blurring of the right heart border (silhouette sign), Triangular density on the lateral view as a result of collapse of the middle lobe, Minimal volume loss with elevation of the left diaphragm, Band of increased density in the retrosternal space, which is the collapsed left upper lobe, Abnormal left hilus, i.e. The right ventricular failure due to pressure overload is considered the primary cause of death in severe PE 14. 24. In some cases, embolectomy or placement of vena cava filters is required. Here another case of diffuse consolidation. 9. This pattern was first attributed to chronic congestive heart failure, but persisted on follow-up CXR's despite therapy. artifact may cause pseudo-filling defects and can be caused by: hyperconcentrated contrast in the superior vena cava, medical devices e.g. Here a patient with septic emboli. The term pneumatocele is used to describe a lungcyst, which is most frequently caused by acute pneumonia, trauma, or aspiration of hydrocarbon fluid and is usually transient. Interstitial edema usually presents as reticulation. Bleeding disorders: leukemia, anticoagulantion therapy, diffuse intravascular coagulation. It demonstrates, that based on the x-ray alone, it is not certain which pattern we are looking at. A PERC evaluation is considered positive if any one of the eight criteria are met. Bibas M, Biava G, Antinori A. HIV-Associated Venous Thromboembolism. Evidently it is very important to recognize the various presentations of atelectasis, since some of them can be easily misinterpretated. J Emerg Med. 29 (1): 31-50. There has been increasing awareness of pulmonary embolism in children with improved survival in children with systemic disease and advancements in diagnostic modalities. A nonfunctioning part of the lung lacks communication with the bronchial tree and receives arterial blood supply from the systemic circulation. HRCT demonstrated honeycombing. This is quite specific for sarcoidosis. Bronchial atresia is a congenital abnormality resulting from interruption of a bronchus with associated peripheral mucus impaction and associated hyperinflation of the obstructed lung (10). When the artery is viewed in its axial plane the central filling defect from the thrombus is surrounded by a thin rim of contrast, which has been called the Polo Mint sign. Just do the work-up of both the differential diagnosis of masses and consolidation. In contrast to acute pulmonary embolism, chronic thromboemboli are often complete occlusions or non-occlusive filling defects in the periphery of the affected vessel which form obtuse angles with the vessel wall 9. Our experience of popliteal vein aneurysm. 2000;174 (6): 1499-508. A practical approach is to divide these into four patterns: In this article we will focus on this four-pattern approach. Notice the air-fluid level indicating pus within the cavity (arrow). Sometimes emphysematous bullae have visible walls that measure less than 1 mm. Remy-Jardin M, Remy J, Deschildre F, et al. This is the typical 'finger-in-glove' appearance of mucoid impaction. This was caused by a large mucus plug. In the lung the vasculitis causes infarcts which first present as ill-defined areas of consolidation. Introduction. False-positive findings in the lung are seen in granulomatous disease and rheumatoid disease. We assume that the atelectasis was a result of post-traumatic poor ventilation with mucus plugging. Here another example of a pneumonia with cavitation. Echocardiography is most appropriately recommended The FDA-approved streptokinase regimen for PE consists of 250,000 U as a loading dose over 30 minutes, followed by 100,000 U/hr over 12-24 hours. Echocardiography may play a significantrole in mak- ing therapeutic decisions in patients with pulmonary embolism. The is volume loss in the upper lobes as a result of fibrosis. Jaff MR, McMurtry S, Archer SL et-al. On a chest X-ray UIP manifests as a reticular pattern particularly at the lung bases. Pulmonary embolism-specific window: Window width, 700; window level, 100 Detailed protocols can be accessed in this AJR article and here. At the end we will also discuss diseases that present as areas of decreased density. (2017) European Respiratory Journal. Pulmonary embolism is a common and potentially fatal cardiovascular disorder that must be promptly diagnosed and treated. Indications. Pulmonary embolism (PE) is the third most common acute cardiovascular disease after myocardial infarction and stroke. The mediastinum has regained its normal position. One rib metastasis is indicated by the arrow. Nov 27, 2018 - Explore Lainey Beeftink's board "Pulmonary Embolism", followed by 158 people on Pinterest. Here we have a patient with atelectasis of the right upper lobe as a result of TB. A common cause of total atelectasis of a lung is a ventilation tube that is positioned too deep and thus obstructing one of the main bronchi. On the CT we can see, that it is a segmental consolidation. Eur. However, literature regarding pulmonary embo … AJR Am J Roentgenol. 2013: 236913. Read "Angiography in Recent Pulmonary Embolism with Follow-Up Studies: Preliminary Report, Radiology" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Since the silhouette of the right heart border is still visible, there is probably partial atelectasis of the lower lobe and not of the middle lobe. Here a typical chest film in a patient with long standing Sarcoidosis (stage IV). 5. 23. Organizing pneumonia (OP) - multiple chronic consolidations. You probably would like to look at old films to see if there are any changes. The chest x-ray shows a nearly total opacification of the left hemithorax. We cannot see the lower lobe vessels, because they are surrounded by the atelectatic lobe. In lesions that do not respond to antibiotics, probably the most important non-invasive diagnostic tool is nowadays the PET-CT. PET-CT can detect malignancy in focal pulmonary lesions of greater than 1 cm with a sensitivity of about 97% and a specificity of 78%. Many would have a lungcancer on the top of their differential diagnostic list. A high probability scan is defined as showing two or more unmatched segmental perfusion defects according to the PIOPED criteria. Pulmonary embolism workup can be ruled out if 1. This makes it difficult to use these terms, since in many cases when we describe a chest X-ray, we are trying to figger out what the pathology could be. Clinical Radiology 16:141-147. Incidence has been estimated to be 0.2 to 0.6 per 1,000 per year. What the radiologist needs to know. The fibrosis persists. The tabel is adapted from chest x-ray - a survival guide. First study the images. Williams JR, Wilcox WC. They are usually horizontal, measure 1-3 mm in thickness and are only a few cm long. 2008;191 (4): 1072-6. Radiology 2005; 237:395-400 . However some patients, who have an acute cardiac infarction, may still have a normal heart size, while other patients who have a large heart due to a chronic heart disease, may have non-cardiac pulmonary edema due to a superimposed pulmonay infection, ARDS, near-drowning etc. The validity of hyperdense lumen sign in non-contrast chest CT scans in the detection of pulmonary thromboembolism. Cumulative damage from repeated embolic insults is a common cause of chronic thromboembolic pulmonary hypertension, which demonstrates a variable degree of the aforementioned signs, but with significantly higher right ventricular pressures, right ventricular hypertrophy and diastolic dysfunction, and a higher degree of tricuspid regurgitation. Infarction - peripheral consolidation in a patient with acute shortness of breath with low oxygen level and high D-dimer. On a Chest X-Ray it can be very difficult to determine whether there is interstitial lung disease and what kind of pattern we are dealing with. Within one month after treatment with antibiotics, there was almost complete resolution of the consolidation and the cavity. See more ideas about Pulmonary embolism, Pulmonary, Deep vein thrombosis. by Au VW, Jones DN, Slavotinek JP. Acute Pulmonary Embolism and COVID-19 Radiology. Small cell lungcancer does not cavitate. We will show a case in a moment. Related to this, Dr. Ahmad is an expert in complex removal of Inferior Vena Cava (IVC) filters. 6. Pulmonary embolism. When these small nodules coalesce, they may resemble consolidation. Created OnSeptember 10, 2017byJonathan Luchs-MD, FACR You are here: KB Home ACR Appropriateness Criteria Cardiac Suspected Pulmonary Embolism < BackRevised 2016 American College of Radiology ACR Appropriateness Criteria® Suspected Pulmonary Embolism Variant 1: Suspected pulmonary embolism. It is also seen in bronchial obstruction caused by an obstructing tumor or bronchial atresia. Diffuse - perihilar (batwing) or peripheral (reversed batwing). Although pulmonary embolism (PE) has been widely studied for many decades, its incidence, mortality, diagnosis, and treatment are still the subject of investigation. Some Kerley B lines are seen. Introduction. However there is also some pleural thickening (red arrow) and vessels seem to swirl around the mass (blue arrows). In this case there are some mass-like structures in the right lung. 2011;27 (3): 433-40. This patient was known to have pleuritic carcinomatosis. Do emergency physicians use serum D-dimer effectively to determine the need for CT when evaluating patients for pulmonary embolism? Continue... Notice the cavitation especially on the right. In the two preceding chapters we discussed chest imaging in patients without a history of injury and in the setting of trauma. {"url":"/signup-modal-props.json?lang=gb\u0026email="}. Pearls and Pitfalls in Emergency Radiology. Are these densities masses or consolidation? Am J Roentgenol Radium Ther Nucl Med. Pulmonary Embolism / DVT / VTE, Radiology & Imaging Add a Comment. Multifocal consolidations are also described as multifocal ill-defined opacities or densities. Diagnosis is straightforward in most cases. When seconds count: interventional radiology treatment for pulmonary embolism saves lives. 1993;189 (1): 133-6. First study the x-rays, then continue reading. (2018) Cardiovascular diagnosis and therapy. On the CXR it is seen as consolidation with cavitation in the apical segments of the upper and lower lobes. 141 (3): 513-7. 15. The thrombus may be calcified. Notice that there are multiple densities in both lungs. In this case there is compensatory overinflation of the left lower lobe resulting in a normal position of the diaphragm and the mediastinum. Med. First study the x-rays and then continue reading. This patient had a several month history of chronic non-productive cough, that did not respond to antibiotics. Intermediate probability with a negative D-dimer or low pretest probability. 3. Emboli may be occlusive or non-occlusive, the latter is seen with a thin stream of contrast adjacent to the embolus. (2017) Journal of the American Society of Echocardiography : official publication of the American Society of Echocardiography. In the left upper lobe there is probably some traction-bronchiectasis due to the fibrosis. (2010) AJR. ACR Appropriateness Criteria® 1 Suspected Pulmonary Embolism American College of Radiology ACR Appropriateness Criteria® Suspected Pulmonary Embolism Variant 1: Suspected pulmonary embolism. They are characterized by linear shadows of increased density at the lung bases. Diagnostic pathways in acute pulmonary embolism: recommendations of the PIOPED II Investigators. Normally when you follow the thoracic spine form top to bottom, the lower region becomes less opaque. This is an uncommon cause of lobar consolidation. Pulmonary Embolism Presenting as Flank Pain: A Case Series. Introduction. When the cysts have thick walls like in Langerhans cell histiocytosis or honeycombing, it frequently presents as a reticular pattern on a CXR. The radiographic features of acute pulmonary thromboembolism are insensitive and nonspecific. The diagnosis, risk assessment, and management of pulmonary embolism have evolved with a better understanding of efficient use of diagnostic and therapeutic options. AJR Am J Roentgenol. 28. The chest x-ray shows total atelectasis of the right lung due to mucus plugging. See more ideas about pulmonary embolism, pulmonary, deep vein thrombosis. The distorted vessels appear to be pulled into the mass and resemble a comet tail (4). Rossi SE, Goodman PC, Franquet T. Nonthrombotic pulmonary emboli. Pulmonary embolism, which is most often caused by blood clots that travel to the lungs from deep veins in the legs, affects as many as 900,000 people each year in the United States. 163(14):1711-7. . American journal of roentgenology. PE most commonly results from deep vein thrombosis (a blood clot in the deep veins of the legs or pelvis) that breaks off and migrates to the lung, a process termed venous thromboembolism … LCH is called a cystic disease. This is the collapsed upper lobe. Impact of residual pulmonary obstruction on the long-term outcome of patients with pulmonary embolism. Anticoagulation is provided in patients without risk of active bleeding. Atelectasis can be the result of fibrosis of lungtissue. The revised PIOPED criteria for the diagnosis of pulmonary embolus indicate the probability of pulmonary emboli based on findings on V/Q scan (ventilation-perfusion scintigraphy). Int J Cardiovasc Imaging. Pulmonary hemorrhage - in a patient with hemoptoe. Usually they vary in size and are well-defined. Large density on the left with loss of cardiac silhouette. Study the images and then continue reading. Notice the similarity between these chest x-rays. Continue with the CT-images. A more practical approach is to describe areas of decreased density in the lung as: Cavities frequently arise within a mass or an area of consolidation as a result of necrosis. Look for other signs of heart failure like redistribution of pulmonary blood flow, Kerley B-lines and pleural fluid. non-HIV matched controls, normal D-dimer has almost 100% negative predictive value (virtually excludes PE): no further testing is required, raised D-dimer is seen with PE but has many other causes and is, therefore, non-specific: it indicates the need for further testing if pulmonary embolism is suspected, abrupt narrowing or complete obstruction of the pulmonary arteries, if absent, another cardiopulmonary derangement is likely responsible, if unequivocally present, it can establish the need for emergent treatment, flattening or dyskinesis of the interventricular septum, CT features suggestive of right ventricular dysfunction include, abnormal position of the interventricular septum, RVD (right ventricular diameter): LVD (left ventricular diameter) ratio >1 on reconstructed four-chamber views, RVD:LVD ratio >1 on standard axial views is not considered to be a good predictor of right ventricular dysfunction, termed submassive PE when right ventricular dysfunction demonstrated on imaging (CT or echo) but without clinical haemodynamic compromise, misidentification of pulmonary veins for arteries, arterial bifurcations (or branch points) can mimic PE but usually easily distinguished on multiplanar assessment.
