All patients are reviewed for contraindications prior to MRI scanning. Medical devices and implants are categorized as MR Safe, MR Conditional or MR Unsafe: [6] MR-Safe – The device or implant is completely non-magnetic, non-electrically conductive, and non-RF reactive, eliminating all of the primary potential threats during an MRI procedure.
Cardiac MRI does not pose any specific risks compared to other indications for imaging. [11] Gadolinium based contrast medium is frequently used in CMR and has been associated with nephrogenic systemic fibrosis, predominantly using linear compounds in patients with renal disease.
The magnet can interrupt the pacing and inhibit the output of pacemakers. If MRI must be done, the pacemaker output in some models can be reprogrammed. [7] In February 2011, the FDA approved an MRI-safe pacemaker. [8] Extracorporeal shock-wave lithotripsy (ESWL) procedure is safe for most pacemaker patients, with some reprogramming of the pacing.

Patients with pacemakers in the U.S. had previously been dissuaded from using MRIs before Medtronic's first SureScan MRI-compatible pacemaker won approval a few years ago. Accoridng to Medtronic's ...
A physician may recommend cardiac imaging to support a diagnosis of a heart condition. Medical specialty professional organizations discourage the use of routine cardiac imaging during pre-operative assessment for patients about to undergo low or mid-risk non-cardiac surgery because the procedure carries risks and is unlikely to result in the change of a patient's management.
