Aims and Objectives: Role of CT Pulmonary Angiography in diagnosis of pulmonary thromboembolism.

Content: Pulmonary thromboembolism (PE) is a frequently occuring disease caused by obstruction of a pulmonary artery by a thrombus. PE is potentially lethal disease. Of all patients who develop PE, it directly causes or contributes to the patient’s death in one-third of the cases. The role of CT in diagnosis of  thromoembolism at different levels of pulmonary trunk involving main trunk, Right pulmonary artery, Left pulmonary artery, saddle thrombus, thrombus involving segmental and sub segmental branches is evaluated.

Summary: The chest radiograph is of limited value. It may be normal or reveal non-specific atelectasis. CT Pulmonary Angiography is preferred imaging modality for diagnosis of pulmonary thromboembolism.
