A research article published in this week's NEJM raised serious concerns about the cancer risks associated with CT scans due to its widespread use in America.
CT sacns are increasingly used in America to diagnose medical problems in children as well as adults, they are needlessly exposed to dangerous radiation that raises the risk of cancer.
The authors said that "too many CT studies are being performed in US" and suggested ways to reduce overall radiation dose from CT including reducing dose in individual patients, using other options and reducing the number of prescribed CT studies.
