Acute pulmonary embolism (PE) is one of the main causes of chest pain referral to emergency departments and among the leading causes of morbidity and mortality among non-neoplastic chest pathologies . Since its introduction, CT angiography (CTA) has become the most reliable, flexible and widespread diagnostic technique to rule out acute PE in the emergency department . CTA has also been proposed as a prognostic tool permitting the risk stratification of patients with acute PE, in particular for its ability to identify ancillary findings that may be integrated with information from vascular analyses . A recently published meta-analysis from Meinel and colleagues describes the importance of these parameters and their correlation with clinical outcome .
