Imaging of Cardiovascular Thoracic Emergencies: Acute Aortic Syndrome and Pulmonary Embolism.

Cardiovascular injuries represent the second most common cause of death among trauma victims in the United States. Motor vehicle collisions account for more than 80% of all blunt thoracic trauma.

This article reviews the clinical entities of acute aortic syndrome and pulmonary embolism, their imaging findings, and diagnostic challenges.
