Ultrasound helps detect deep vein blood clots

Italian researchers say the finding gives emergency room doctors and hospitals an easier way to check for the clots that can kill.

Until now, most doctors relied on a costly and time consuming technique to test for deep vein thrombosis.

New research in the Journal of the American Medical Association says the easier ultrasound is just as effective.

A deep vein clots happen when circulation is often restricted in the legs. Catching the clot before it moves through the body to the lungs can prevent death.
