Medtronic 780/Guardian 4 and MRI

Hi,

I’m reaching out for your help and advices.

My partner is diabetic type 1, and currently with the Medtronic 780 insulin pump and the Guardian 4 CGM.
She is a vet surgeon and currently undertaking a specialisation to become a specialist in Imagery (which include X-ray, scanner, ultrasound and mri technology).This year will be « hands on » training and will require her to be in the MRI room to install patient in the MRI). She will only be in the room to instal patients, then will go to the control room to operate the MRI.

We have received conflicting information from Medtronic and her doctor if being in the MRI room to just install the patients (not when the MRI is imaging) would cause issue to her pump, the CGM or injection site). As we know even when not active the MRI magnets are still effective and could damage or pull out her materials, or damage the CGM in a way that it does not measure or tramsits accurate info.

We want to be 100% about what to do and the best way forward. She doesn’t want to give up on her dream job but if that means removing all her pump materiel and captors each time she has to give an mri, it’s impossible.

Any suggestions is welcome 🙂

Thanks a lot for your help and guidance.
 
I have regular scans and am always told pump/sensors can not even go into the MRI room. All have to to be removed before entering the room. Canula can stay in as long as it's not a metal canula.
 
I believe Abbott recently sent out a directive to say that Libre sensors could now remain on during scans. Hopefully someone will correct me if I am wrong. Obviously they are only talking about their sensors, so you would need to take advice from Medtronic for their pump and sensors. Perhaps @SB2015 who uses a Medtronic pump will know.
 
I do use the Medtronic HCl and for MRI i have removed both the pump and sensor. The pump has been given to the radiographer before entering the room and it has gone in another room.

For any other scan or X-ray I have removed the pump once in the room and given it to the radiographer and chanced leaving the sensor in where the X-ray is not being taken of my upper arm. So far the sensor has survived and kept going until changeover was required.

I don’t know whether I am being over cautious, but better safe than sorry.
 
I had an MRI on my knee today and was asking them about sensors, pumps etc and they said that even when the scanner is not actually operating the magnet is still on which is why sensitive devices can't go in the room as they may be affected by the strong magnetic field.

Looks like Libre are the only sensors as of 15th Nov 2024 that are authorised to stay on during MRI scanning.

Can You Wear a CGM During an MRI? If It’s Ours, You Can. | Abbott Newsroom

FreeStyle Libre 2 and 3 systems for people with diabetes are the first patient-applied CGMs in the U.S. approved to wear during imaging scans such as MRIs and mammograms.

That is talking about having scans in the US so I wonder if that would be applied to the regulations and requirement imposed by the NHS for scan here. It can often take a long time for the NHS to catch up with any directive when it would require a change of procedure.

I think some people received an email from Abbott recently advising that it can now be used in MRIs here too.

That doesn't seem to have filtered down to the people doing the MRI as if I had had one I wouldn't have been able to keep in on in the scanner even though it was only my knee that went in the instrument.
