An image produced by a CAT scanner. Also called CT scan. Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures of the body
More research on risks and benefits of medical imaging needed – Researchers are evaluating the risks and benefits of medical imaging in patients. They revealed that the average effective dose of radiation nearly double the amount they would otherwise be exposed to from natural sources.
OHSU researchers find regular MRI, CT, radiography scans unnecessary unless a significant underlying condition is first identified. – Physicians should not immediately order routine scans for low-back pain unless they observe features of a serious underlying condition, researchers in the Oregon Evidence-Based Practice Center at Oregon Health & Science University report.
A recent article in the New England Journal of Medicine has suggested that the radiation dose from CT scans is a cause for concern, and CT scans should only be used judiciously and when medically necessary.
– A recent article by Drs. David Brenner and Eric Hall in the New England Journal of Medicine has suggested that the radiation dose from CT scans is a cause for concern, and may be responsible for a small percentage of cancer deaths in the United States. While the conclusions of the Brenner article have been portrayed by some as conclusive, in reality the scientific community remains divided in regards to the radiation dose effects of CT.
