Abstract

Multidetector computed tomography (CT) plays an important role in the detection, risk stratification and prognosis evaluation of acute pulmonary embolism. This review will discuss the technical improvements for imaging peripheral pulmonary arteries, the methods of assessing pulmonary embolism severity based on CT findings, a multidetector CT technique for pulmonary embolism detection, and lastly, how to avoid overutilization of CT pulmonary angiography and overdiagnosis of pulmonary embolism.

Key Points

We describe clinical prediction rules and D-dimers for pulmonary embolism evaluation.

Overutilization of CT pulmonary angiography and overdiagnosis of pulmonary embolism should be avoided.

We discuss technical improvements for imaging peripheral pulmonary arteries.

Pulmonary embolism severity can be assessed based on CT findings.

We discuss multidetector CT techniques for pulmonary embolism detection.
