395 Is Lower Extremity Venography Necessary in Pulmonary Embolism CT Imaging?

Study Objective: Pulmonary thromboembolism (PTE) is the third most mortal disease after acute myocardial infarction and cerebrovascular events. Ten percent of patients with pulmonary embolism also have deep venous thrombosis (DVT). Point-of-care compression ultrasound (PoCUS) is performed in the emergency room to detect the DVT of the patients, and doppler ultrasonography is performed by the radiology physicians. In addition to pulmonary computerized tomography (CT) angiography, lower extremity venography is also performed.
