The sensor, transmitter, receiver or insulin pump should not be exposed to x-rays, CT scans, MRI, any radiation and/or strong electromagnetic fields.

What do I do if I have to have an x-ray, CT scan or MRI or have any procedures with radiation or strong electromagnetic fields?

You must remove the sensor/transmitter attached to your body before the test. You will have to insert a new sensor after the test. You should plan to do this at home if possible as there may not be enough time or space for you to do this in the test area.

Remember, all of the components of your CGM or monitoring system could be damaged and must not be exposed to x-rays, CT scans, MRI, any radiation and/or strong electromagnetic fields.
