Why Is It Unsafe For Someone With A Pacemaker To Have An Mri Scan
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
Arrhythmia: Pacemakers work by electrical impulses and are affected by strong electromagnetic fields. Mris work by strong electromagnetic fields, so having an MRI with an implanted pacer can be life-threatening.

51 yr old brother had pacemaker implanted after 6 fainting-flatlining episodes. Mri/ct scan showed brain/heart not the problem. Why is this happening
Not sure.: Pacemakers not implanted without very specific indication. Mri/ct scanning is not expected to demonstrate any abnormality for fainting or flatlining. Ask electrophysiologist and interventional cardiologist who implanted the device. Your brother should no longer have fainting after implant. Continued symptoms suggest another cause....Seizure? Psychiatric? ...Read moreSee 1 more doctor answer

If you are getting IV contrast they will need to know about kidney fx ...Read moreSee 1 more doctor answer
Ask your provider: While open MRI can be an option, the magnet is much weaker than closed mri. This means the picture quality is not as good, like the difference between an inexpensive camera and a professional one. For some areas of the body, the open is okay. For others (spine in my practice) the higher quality is critical. Sedation can be used to deal with claustrophobia. Your provider can guide you. ...Read moreSee 2 more doctor answers
MRI: Ask your doctor. Apparently blood tests and or physical exam or other imaging studies such as ultrasound prompted the decision to pursue the mri. The physician who ordered the MRI is the most appropriate person to resolve the question as to why it was ordered. ...Read moreSee 1 more doctor answer
