Protection from high-dose radiation

DENVER, July 19 (UPI) -- A U.S. radiology expert says healthcare providers are finding ways to protect patients from high-dose radiation.

Dr. Simeon Abramson, lead heart computed tomography radiologist at Denver's Porter Adventist Hospital, says concern about the health risks of commonly used scanning tests involving high doses of radiation has led doctors and technicians to seek ways of decreasing radiation exposure.


At Porter, Abramson and colleagues have succeeded in reducing the dose of radiation for computed tomography heart scans from the equivalent of 100 to 140 chest X-rays to the equivalent of 10 to 30 X-rays. This is done in part by turning off the X-ray during parts of the rotation that target sensitive areas, such as organs.

"We learned that it was possible to use software within our system that allowed us to reduce the radiation exposure in CT heart scans for most of our patients. The quality of the image has not been affected and we know that we are protecting our patients from potential harmful doses." Abramson says in a statement.
