CT Scans Deliver More Radiation to Obese People: Study

FRIDAY, April 13 (HealthDay News) -- Obese and overweight patients who undergo CT scans are exposed to much more radiation than people of normal weight, researchers say.

The challenge for heavier people is that more radiation is needed to scan their bodies, a radiation specialist said.

"One has to customize the dose based on patient size, increase the power of the X-rays and the quantity that are going inside," said Dr. Dushyant Sahani, director of CT imaging services at Massachusetts General Hospital and an associate professor of radiology at Harvard Medical School.

Nearly 60 percent of U.S. adults are overweight or obese, according to the study. As obesity-related health challenges surface, so do orders for medical scans, the authors said. Because radiation can cause cancer and other ill effects, researchers have been concerned about the risks of exposure derived from medical imaging.

However, Sahani, who was not involved in the study, said the excess body fat of extra-large patients absorbs much of the radiation, meaning that they may face no extra danger.

"Fat is not as sensitive to undergoing any bad changes as the other tissues," said Sahani.

Even if an obese patient gets twice the radiation as a smaller person of the same age, the risk of radiation damage would be higher for the smaller person, he said.

The study authors, all from the Rensselaer Polytechnic Institute in Troy, N.Y., launched their research to better understand how radiation in CT scans affect the bodies of heavier people. Statistics about their radiation haven't been previously available, the study authors said. "We want to fill this gap," said study lead author Aiping Ding, a research associate at the institute.

CT scans are used to create images that divide the body's organs into sections, or slices. Sahani said, "They produce a detailed anatomic picture, as if someo
