CT venography and angiography for an optimal diagnostic approach to venous thromboembolism

Dear users,

Deep vein thrombosis and pulmonary embolism are strictly interrelated pathologies as they are attributable to the same spectrum of disease, namely venous thromboembolism (VTE). Although VTE is often clinically silent, it may also present as massive embolism leading to death.

The most reliable diagnostic procedure for VTE is MDCT. In particular, CT venography is widely used to evaluate the status of the venous system. With its very high contrast resolution and anatomical detail, MDCT venography enables radiologists to accurately identify and characterize the pathological processes. The utility of this diagnostic tool is illustrated in Dr. Anzidei’s latest Focus on, in the selection of literature and in the clinical cases reported in this newsletter. A comment on a recent meta-analysis and the e-book here proposed support the usefulness and advantages of CT angiography for the diagnosis of pulmonary embolism.

We remind you that suggestions for new topics to be covered in future issues are welcome: please contact us at

CT angiography for acute pulmonary embolism: what should radiologists look for beyond the embolus?
M. Anzidei

Acute pulmonary embolism (PE) is one of the main causes of chest pain referral to emergency departments. Since its introduction, CT angiography has become the most reliable, flexible and widespread diagnostic technique to rule out acute PE in the emergency department and has been proposed as a prognostic tool for the risk stratification of patients with acute PE, as described in a recently published meta-analysis. view »
