CT of pulmonary embolism: Imaging update

Abstract

This article provides an update of the current trends in the management of acute thromboembolic disease, aimed at emphasizing new options applicable in daily practice. CT is no longer exclusively dedicated to the diagnosis of PE but also participates in the prognostic approach of this disease focusing on the detection of CT features of right ventricular dysfunction. The availability of perfusion CT allows evaluation of the extent of perfusion impairment, thus introducing a more reliable prognostic parameter than the estimation of the clot burden. Radiologists can provide clinicians with relevant information regarding the early risk stratification that is worth describing in daily practice. Optimized management of young patients, pregnant women, and evolution toward chronic pulmonary embolism will also be covered in this chapter.
