Multidetector CT pulmonary angiography features of pulmonary embolus.
Pulmonary embolism (PE) is a life-threatening condition. Multidetector CT pulmonary angiography is currently the imaging method of choice for the detection of PE. The aim of this pictorial essay is to review the appearances of PE on multidetector CT pulmonary angiography, including signs that differentiate acute and chronic PE and markers of severity. The features of a non-diagnostic study and pitfalls leading to a false-positive or false-negative study are presented.
