CT Scan

A computed tomography or CT scan is used to examine veins and arteries to detect problems with blood flow, and the presence and location of blood clots. It is commonly used to diagnose pulmonary embolism (PE) and sometimes deep vein thrombosis (DVT).

CT scans are performed in the Radiology Department and take approximately 30 minutes. Before the test, an intravenous line is set up in the arm, so that a contrast dye can be injected into the bloodstream while the CT images are being taken.

Because PE can be fatal without treatment, the benefits of diagnosing PE outweigh the potential risks of the procedure, even in patients who are pregnant. Your physician will discuss potential risks prior to the procedure.
