    Hello my name is Michelle.


    I am writing to find out whether anyone else who uses the Abbott Libre Sensors has had to have an MRI.


    The reason I ask is , I had to have an MRI two weeks ago and had changed my sensor the night before as I has knocked the sensor I had on off.  


    I went to have the MRI and was told I had to take the sensor off.  I said I had just changed it the night before. I was having an MRI on my foot not of my arm.  The radiographer insisted it had to come off.


    I was very annoyed by this.  He said have your doctor write to the radiography company stating you had to take it off and they will allow me to obtain another sensor?  This is so frustrating.   Of course the radiography company is not going to reimburse me.


    I am interested to hear from others.  I have to have another MRI in two weeks.  I have started using my old blood glucose machine, so I do not waste another $92.50.

    Hi Michelle !

    Had the same experience. They have a list of devices which can be worn during an MRI. Unfortunately the Libre Sensor is not on the list.

    Not sure why, but goodbye $92.50 !

    Hi Everyone,

    FYI - Dexcom can’t be worn for MRI or X-rays either. I did ring AMSL up before going and checked to be doubly sure.

    Dear all re MRIs and sensors,
    MRI stands for Magnetic Resonance Imaging. The process uses intense and changing magnetic fields to build images of your interior. The software to do that is amazing.

    One of the main effects of a changing magnetic field is inducing an electric current in metals. That is how the older transformers work to change 240 volts to 5 volts or 24 V.

    So, you are asked to remove jewellery, watches, glasses etc., and sensors that contain metal because of both the electric currents the magnetic fields would cause and if any magnetic materials were in them ( Iron, Cobalt, Nickel) they would be attracted by the intense magnetism. The fields are INTENSELY strong.

    That is one of the reasons that hips and knees contain only Titanium. It is non magnetic and neither is Gold or Silver (dental fillings).

    Precaution is the main game in removing everything that is removable.

    Hope this helps you plan your future MRIs.

    Hi David thank you for that that was very informative. Does that mean that because I've got titanium in my leg I could still have an MRI?

    Hi Catherine,
    It is non magnetic but a current could still be induced in it. I would talk to your doctor and to the radiologist. 

    My approach is : when in such positions, tell them everything before going for the appointment.

    I have a Dexcom G5. Checked with AMSL before I had a bone density scan They can be worn only during an ultrasound, no other imaging situations. I assume it is the same with all CGMs and that it would interfere with the transmitter or fry components. Luckily I had only one day to go with mine but the day adjustment sets me up for my next screen in a week where I will only miss a couple of hours.
    Hope all results are 😊

    I had an MRI a few weeks ago and had to remove my Medtronic CGM.  It too was only a day old.  I called Medtronic and they replaced it no questions asked.

    It is an undeniable fact that MRIs are scheduled for one day after a new sensor is fitted !  🤣

    Hi, I use the Medtronic sensors and have also had two MRIs. The first time I was told I had to take it the sensor off. The second time I was told to time the MRI so that it could done between sensors. I think fundamentally it is a case of us being aware that we will have to remove them and time the MRI to suit.

    Hi Michelle,
                             I have had an MRI and declared my sensor and was told it was ok.  This was at a public hospital.

    Hey Team, Can we get a definitive answer from someone who knows and the reasons why/why not would help.  Thanks, Helen

    Helen,

    When I had an MRI the operator had a list. I don't know the origin of the list but I suspect, based on the stories of inconsistencies in procedure, they made it up themselves.

    The reality is that the governing body of these services, the "Royal Australian and New Zealand College of Radiologists", should provide guidance in their "Standards of Practice for Clinical Radiology, Version 11.2". Unfortunately there is nothing in this document to provide guidance, so,  each practice has to make up their own list of approved devices.

    This leads to inconsistency. The suitability of each device for MRI is probably left up to someone with limited knowledge and no ongoing responsibility for reviewing new devices.

    It needs to be changed, doesn't it ?

    Good morning to you all, 
                                               I understand your concerns, we are all in the same boat but I only learnt recently of a food that I have avoided for 40 years. 
                                               A dietitian told me to have honey.  I only use a drop before bed, (enough to sit on the top of a cut banana) I was told that it is the slowest carb to be absorbed so lasts longer than lollies. 

    Regards Don

    I have always been advised to remove pump and sensor when having MRI, X-ray etc.
    Your device maybe destroyed if  you continue to wear them.

    Hi Michelle, I have a CGM and had to have 3 MRI's last year. I had to remove it the first time and made sure it wasn't on me the next 2 times. I think it is because there are concerns with metal being in the sensor and the MRI being magnetic. They wouldn't let me take crutches into the room for this reason . It's not the radiography company's fault they are just being safe.

    Hi ! I just sent this to the Royal Australian and New Zealand College of Radiologists. Maybe someone there can reply with a sensible answer.

    "When a diabetic using CGM or FGM devices ( typically Medtronic or Freestyle Libre ) is scheduled for an MRI they are generally required to remove the sensor prior to the MRI.

    The requirement appears to be quite ad-hoc and I cannort establish any defined criterion for this requirement.

    Who defines which devices need to be removed prior to MRI procedures ?

    Are medical stents for cardiac treatment included ? What about hip or knee replacements ?

    Surely your document "Standards of Practice for Clinical Radiology, Version 11.2" should be expanded to include a list of medical devices which can be worn during MRI procedures.

    The current situation, as I understand it, is that due to the lack of an industry standard each practice has to make up their own list of approved devices.

    Surely as a professional organisation you should step up and develop a standard, which is capable of being updated to embrace new devices and technology, and avoid what appears to be an ad-hoc approach.

    I await your response."

    Hi all,
    Check this site for answers. Also covers CT scans, which are preferred for older devices. I always get asked if I have a pacemaker when I go for one. My brother has a newer one. It is put into Safe Mode and reprogrammed after the MRI.

    Hi Paul,

    I have been told that the heat from some procedures can affect the various glucose monitors. It’s not a ‘who decides’ scenario, the manufacturers need to ensure that we know which procedures will and won’t possibly mess with our monitors. Can be confusing!

    Cheers

    I had the same thing happen to me last year. I called free style Libre and they sent a replacement 
      Hope it works for you

    Hi everyone, I had to have a brain scan recently and I had just changed my Freestyle Libra sensor that morning. My scan was scheduled for 4.00 pm that day. I had to remove my gold necklace, with my Medicalert necklace, which I accepted. But I then was instructed to remove my sensor, which I had no notice of and I reluctantly did so. I am fortunately receiving sensors free as a 79 year old Type 1 on Age Pension . But I must agree with those who must pay for their sensors that notice should be given that sensors must be removed as their microwave signals  may interfere with the  sensitive MRI scanning devices. This advice could be simply issued with the paperwork provided with the online booking stuff for everyone irrespective of wearing sensors or not. The advice will be non discriminatory then.

    Whilst I agree it is really inconvenient to have to remove a sensor (and I'm self funded) I do feel we need t
