A venogram is a way to look at veins in your body using x-rays and a special dye called contrast. It is most often use to look at veins in the legs and belly area (abdomen).
Veins are not normally seen in an x-ray. That is why the special dye is used. The health care provider injects this dye into a vein so it shows up better on x-rays.
Some people may have an allergy or reaction to the dye used during a venogram. Patients at risk include those with shellfish or iodine allergies. Before the procedure, tell your doctor about any allergies you may have.
