    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 !  ðŸ¤£
