We do not recommend that you use any of the CGM components (sensor, transmitter, and/or smart device) for magnetic resonance imaging (MRI), computed tomography (CT) scan, or high-frequency electrical heat (diathermy) treatments. The CGM Signos uses, the Dexcom G6, hasn’t been tested in these situations. The magnetic fields and heat could damage its components, which may cause it to display inaccurate glucose readings.
To properly prepare for a procedure of this nature, you can either time the procedure with your next sensor replacement or stop your sensor early. For more information on how to stop your sensor early, check out this article.
If you choose to go forward with the procedure while still wearing an active CGM, you assume the risk of any damage.
