They proposed that of the estimated 61.5 million people who got CT scans in 2023, eventually 103,000 would develop cancer linked to radiation exposure.

One CT scan can expose a patient to 10 or 15 times as much radiation as another, Smith-Bindman said. “There is very large variation,” she said, “and the doses vary by an order of magnitude ...

CT scans are a common test used by radiologists to examine what's happening inside the body. These scans use a small amount of radiation, raising concerns that they could cause cancer. Mark ...

From September 2020 to December 2022, 54 immunocompromised patients with fevers were referred to Dr. Klug's division to undergo two chest CT scans: a normal-dose scan and an ultra-low-dose scan.

At similar radiation doses, ultra-low-dose chest CT provides superior image quality over chest x-rays in children with cystic ...

Unnecessarily high radiation doses in CT scans have been linked to cancers. Under new federal rules, doctors and imaging centers have to more closely track and report the doses that patients get.

“We keep doing more and more CTs, and the doses keep going up.” One CT scan can expose a patient to 10 or 15 times as much radiation as another, Smith-Bindman said.
