A venogram is a way to look at veins in your body. It uses x-rays and a radiographic contrast material. It is most often used to look at veins in the legs and belly area (abdomen).

Veins are not normally seen in an x-ray. That is why the contrast material is used. The health care provider injects this dye into a vein so it shows up better on x-rays.

Alternative Names



Tell your health care provider before the exam if you have diabetes or kidney problems. These conditions increase the risk of injury to the kidney. If you are taking metformin, you need to stop taking this medicine before you get radiographic contrast material. Talk to your doctor before stopping or changing your medicines.

Some people may have an allergy or reaction to the contrast material. Before the procedure, tell your provider about any allergies you may have.
