I have an MRI today. I mentioned my OmniPod pump and was told I would have to remove it. I forgot about my CGM, I’m sure they’re not going to like that either. Has anyone had any experience with this?

As mentioned in my other post, I would remove CGM as well. I don’t believe the G5 has been tested in an MRI environment and the components of the transmitter could be damaged by the MRI.

You should be fine with the sensor, in terms of safety—there’s no metal in it, so shouldn’t cause any problem with the imaging or get pulled off/go flying (the main safety concern with MRI, since even small metal objects can become dangerous projectiles). If the sensor gets damaged, you’re no worse off than you’d be if you removed it prior to the MRI. I would however click out the transmitter though for the scan, mostly to prevent potential damage to the transmitter, which would be a lot more unfortunate.

Only exception I can think of is they might be pickier if the sensor is on the area they are imaging, but even then in theory shouldn’t matter.

I do MRI research, and that’s what I would have a participant do… your techs may vary.

Oh, and if you take out the transmitter, this is probably obvious, but leave it with your belongings outside of the MRI room/away from the magnet.

I knew I read it somewhere before!!!

Directly from Dexcom:

_MRI/CT/ Diathermy _
Remove the Dexcom G5 sensor, transmitter, and receiver before Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scan, or high-frequency electrical heat (diathermy) treatment. The Dexcom G5 has not been tested during MRI or CT scans or with diathermy treatment. The magnetic fields and heat could damage the components of the Dexcom G5, which may cause it to display inaccurate blood glucose readings or may prevent alerts.

_The system hasn’t been tested during MRI, CT scans, or with diathermy treatment. Magnetic fields and heat could damage the components, stopping sensor glucose readings or Alarm/Alert notifications. Without sensor glucose readings or Alarm/Alert notifications, you might miss a severe low or high glucose event.

Thanks, guys. Removal it is!

I had one a few months back and they told me I couldn’t have any of it and had me remove and leave it all in the locker with my clothes, including the CGM transmitter. It was within a day or so of being the end of a sensor session anyway, so I just pulled the whole thing.
