Radiation Levels High in CT Scans

Posted:

A new study finds that CT scans may give patients high doses of radiation.  CT scans take dozens of images around the body and are commonly used to diagnose heart disease.  Although radiation levels differed from hospital to hospital, the average radiation dose for one CT scan was equivalent to 600-chest x-rays.  While the risk of developing cancer after a CT scan is less than 1%, researchers say doctors could be doing more to minimize their patient's radiation exposure.

Researchers analyzed radiation exposure at 50-hospitals for the study.
