FDA Updates Data on Interference between CT Scans and Medical Devices

​The U.S. Food and Drug Administration (FDA) recently updated its 2008 information on a rare, preventable type of interference between computed tomography (CT) imaging and electronic medical devices, including insulin pumps, cardiac implantable electronic devices, and neurostimulators. While FDA has received a small number of reports of adverse events related to CT imaging and wearable electronic medical devices, the agency states that "the probability that this interference can cause clinically significant adverse events is extremely low." FDA observes that interference can be completely avoided when the medical device is outside the primary x-ray beam of the CT scanner.
