Venogram

What To Think About

• Doppler ultrasound is often the first test done to look for blood clots in the veins of the arms or legs. Venography may be done when another test, such as ultrasound, cannot give a clear picture of the veins.
• Some X-ray departments use computed tomography venography (CTV) or magnetic resonance venography (MRV) instead of the more standard X-ray venography.
