How the test will feel:

The x-ray table is hard and cold, so you may want to ask for a blanket or pillow. You will feel a sharp poke when the intravenous catheter is inserted. As the dye is injected, you may experience a burning sensation.

There may be tenderness and bruising at the site of the injection after the test.

Why the test is performed:

This test is used to identify and locate thrombi (blood clots) in the veins of the extremity that is affected.

Ultrasound is a newer procedure with fewer risks and side effects, and it is used more often than lower extremity venography.
