FDA Warns of CT Scans on Implants


Published Date : Apr 11, 2016

The global implantable medical devices market is in full bloom currently. This has to do with the recent technological jumps that have significantly improved the utility, scope, and efficiency of implant devices. The materials that can be used have advanced as well, allowing manufacturers to reduce the size of these devices to ensure a better fit inside the body. Another reason why this market is booming right now is the lack of substitutes. As with any other market, the global implantable medical devices market can always be challenged by the availability of cheaper or more effective alternatives. This, however, is such a restricted talk for medical implants, because there are almost no substitutes to artificial mechanisms being used in the human body. Getting a transplant organ in today’s medicine is increasingly difficult, as the number of patients that require transplants only seems to increase by the day. Medical implant device still remain the top option as treatment for severe injuries and organ replacement.

FDA Warns of CT Scans on Implants
Last month, the FDA had issued a warning against the use of a CT scanner on patients that have medical implant devices. Although in the warning issued, the FDA stated that the chances of something seriously bad to happen over a CT scan. They have a small list of complications that could occur in the event a medical implant device is bombarded with radiation. These devices include pacemakers and implantable defibrillators, insulin pumps, and neurostimulators. According to the FDA, the radiation showered on a patient during a CT scan could cause the implants to malfunction by affecting its circuitry adversely. The CT scanner could even affect a wearable medical device outside the body.

However, the FDA stated that the chances of a CT scanner causing major damage to an implant device and the patient are little to none. There is little evidence that the irradiation could have adverse effects on a clinical level on the implants consistently. There are always risks associated with exposing a piece of electronics to an external energy field or radiation, but so far, there are little signs of the CT x-ray showing any harmful effects on implants.
