Pelvic scan not needed for finding blood clots

May 4, 2011
The pelvic area of the body can be eliminated from imaging tests for blood clots without reducing the effectiveness of the scan, according to findings presented before the American Roentgen Ray Society.

Researchers have found that the reduction of radiation exposure achieved by eliminating the pelvic region from a scan during CT venography, an imaging test that checks for venous thromboembolism (VTE) - outweighs the need to include that part of the body in a scan.

Blood clots in the veins usually form in the legs and need to be treated before becoming life-endangering if they reach the lungs.

"Radiologists and technologists can eliminate pelvic imaging while acquiring only images of the lower extremities with CT venography, starting from groin to below the knee," said Dr. Charbel Ishak, in a news release from the society. "We believe that by stopping the imaging of the pelvis, we can decrease patient radiation dose without significantly affecting the diagnosis of VTE."

In the study, researchers reviewed data on 1,527 people who were examined for venous thromboembolism at the Nassau University Medical Center in East Meadow, New York, which is an affiliated hospital of the North Shore-LIJ Health System. Only five people were found to have VTE in the pelvic area.
