It is possible for damage to occur after an MRI in a patient wearing an insulin pump. Insulin pumps contain metal components, and when the insulin pump is exposed to a strong magnetic field such as an MRI it may damage the core components of the insulin pump, resulting in damage to the machine and causing abnormal dosage of medication to be infused, among other things. Therefore, it is necessary to remove the insulin pump before the MRI examination and put it back on after the examination, and at the same time, the blood glucose concentration should be monitored at regular intervals. In addition to this, radiological examinations such as X-ray and CT examinations may also damage the insulin pump, so patients are also advised to remove the insulin pump before such examinations. Patients wearing insulin pumps who need to undergo MRI are advised to do so under the guidance of a doctor.
