No more than I would be compatible with Cruella de Vil.

Oh, you were asking if you can you have a magnetic resonance imaging (MRI) test performed if you have an implant.

I can’t say from personal experience, but researchers at St. Gallen Canton Hospital, in Switzerland, conducted a study that found that high-frequency (HF) 13.56 MHz RFID tags do not significantly interfere with the functionality of imaging devices, nor do those devices affect the tags’ functionality. The study, undertaken by physicians and researchers at the hospital, as well as at the University of ETH Zurich, determined that MRI radiation could raise the temperature of tissue around an RFID tag by, at most, 4 degrees Celsius (7 degrees Fahrenheit), but that it had no effect on a patient’s health (see Swiss Study Finds RFID Tags Safe for MRI, CT Scans).
