Study Released at RSNA Shows CTs May Cause Excess Radiation Exposure

by Astrid Fiano, DOTmed News Writer | November 30, 2009

The RSNA notes that major efforts continue to protect patients from excess radiation exposure due to medical imaging procedures, including the Image Gently initiative (for pediatric radiology) and an ACR-RSNA task force for adult radiation protection.

However, Dr. Guite also advised patients not to be alarmed if their physician orders a CT exam. "The use of CT has been a huge benefit to human health," she said. "When used appropriately, the benefits of the diagnostic information obtained with CT far outweigh the potential risks."

We repair MRI Coils, RF amplifiers, Gradient Amplifiers and Injectors.

Dr. Hinshaw then suggested that patients ask their physicians about the risks and benefits of the proposed imaging, and also ask the CT facility about the number of series to be taken, and if a smaller number would be sufficient.

Coauthors of this study are Frank N. Ranallo, Ph.D., and Fred T. Lee, M.D.
