Is a Pacemaker/Defibrillator a Contraindication to MRI?

As our population is getting older, more patients rely on cardiac-implanted devices. It is common to see these patients in the spine clinic, where advanced imaging is required for accurate diagnosis. Is it safe to use MRI in these patients?

The current practice is to avoid Magnetic Resonance Imaging (MRI) in these patients since the presence of an implanted cardiac device is considered a contraindication, which in result, would harm the patient.

Lateral Lumbar Interbody Fusion (LLIF)

Lateral lumbar interbody fusion (LLIF) is a minimally invasive spine (MIS) fusion procedure used to remove pressure from the pinched nerves, realign and stabilize bones in the lower back. It is known under several different names depending on the manufacturer of the equipment, including LLIF, XLIF, DLIF.

How is the procedure performed?

As discussed in a separate article, MIS surgery achieves the same goals of traditional “open” surgery while resulting in less damage to body.
