High Res Heart CT Scans Risk for Patients

With more and more technologies becoming available, doctors are finding that they must increasingly weigh the side effects of testing procedures.

After gaining FDA approval in 2004, CT angiography, a high resolution scan of the heart for blocked arteries, has been much more widely used. However, there is a risk–especially to younger people, as these scans expose patients to 20 times the amount of radiation as a mammogram.

Researchers reported that a CT angiography should be used sparingly, especially on young women, who have a 1-in-143 chance of developing cancer after just one high resolution CT scan.
The study was published in the Journal of the American Medical Association.
