G7 CGM System

Percutaneous interstitial-fluid glucose monitoring system, electrochemical

No MRI/CT/diathermy — MR unsafe:Don't wear any Dexcom G7 CGM System component during magnetic resonance imaging (MRI) or high-frequency electrical heat (diathermy) treatment. However, it's safe to have a CTscan if you keep the sensor out of the scanned area and cover the sensor with a lead apron during the scan.

The Dexcom G7 CGM System hasn't been tested in those situations when used during an MRI scan, diathermy, or in the scanned area of a CT scan. The magnetic fields and heat could damage components of the Dexcom G7 CGM System, which may cause inaccurate sensor readings or prevent alerts. Without sensor readings or alerts, you might miss a severe low/high glucose event.
