Cancer Patients Diagnosed With Unsuspected Venous Thromboembolism (VTE) on Routine Computed Tomography (CT) Scans

This is a prospective study with the following objectives: Primary Objective: 1. To estimate the prevalence of unsuspected VTE in oncology patients on routine staging CT scans of the thorax, abdomen and pelvis. Secondary Objectives: 2. To identify symptoms commonly associated with VTE that are present in cancer patients undergoing routine staging CT scans with findings of unsuspected VTE. 3. To identify the risk factors and demographic characteristics in outpatient cancer patients associated with the development of unsuspected VTE. 4. To determine the incidence of recurrence of new VTE in patients with unsuspected VTE at 3 and 6 months of follow-up.
