title: Computed tomography of pulmonary embolism.
abstract: Pulmonary embolism(PE), a blockage within the bloodstream in the lung, is a frequent complication of deep vein thrombosis. It is often asymptomatic and can kill without warning. PE patient survival frequently depends on rapid clinical assessment and, when indicated,timely diagnostic imaging.Multidetector computed tomography pulmonary angiography (CTPA) plays an increasingly important role in the diagnosis of suspected PE. Imaging personnel must be familiar with the risk factors, diagnosis, and treatment of this deadly and often unrecognized condition.This article describes PE epidemiology, pathophysiology,diagnostic imaging decisions,and multidetector CTPA techniques.
