Vein Scan

Fibrinogen Uptake Study

What To Think About

• Other tests, such as Doppler ultrasound and venography, are often used instead of a vein scan to detect blood clots. The Doppler ultrasound provides quick and accurate results without the use of radiation, but unlike a vein scan, it may be less accurate at distinguishing an old clot from a newly forming one. However, if the results of those tests are not clear, a vein scan may be done to confirm the location of a newly forming blood clot, especially for a person who has recurring blood clot problems. For more information, see the medical tests Doppler Ultrasound and Venogram.
• A vein scan may be done for a person who cannot undergo venography because of a history of severe allergy to contrast material.
