Venogram

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

• Pregnancy. A venogram is not usually done during pregnancy because the radiation from the X-rays could harm the baby.
• The inability to stay still during the test.

Arm or leg venogram

• Putting any weight on the leg being tested may stop the dye from moving through the leg veins properly.
• Moving your arm or leg may affect how the dye moves.
• In rare cases, foot veins are too small to put the dye into for the test.

Kidney venogram

• Stool (feces) or gas in the intestines (bowel) may make it hard to see the kidney veins clearly.
