A small number of reports have been received by the FDA regarding “adverse effects” thought to be associated with CT imaging of wearable and implantable medical devices such as neurostimulators, insulin pumps, and cardiac implanted devices.
If the CT scanner irradiates the circuitry of certain devices it can cause enough interference to affect the operation of the device. However, the likelihood of that happening is very low and the FDA believes that the benefit of CT scanning greatly outweighs the odds of such an event.
Professionals and patients are asked to complete and submit a report of any side effects. To learn more, please read the FDA’s safety alert: http://www.fda.gov/Safety/MedWatch/SafetyInformation/SafetyAlertsforHumanMedicalProducts/ucm493739.htm
