What are the contraindications to performing cardiac MRI?
Cardiac MRI is contraindicated in most patients with intracranial or intraocular metal or shrapnel, cochlear implants, most pacemakers or defibrillators, and some older prosthetic valves. Pregnancy is a relative contraindication, although it may still be performed when the benefit to the mother is greater than the unknown risk to the fetus. However, gadolinium-containing contrast material is contraindicated in pregnancy.
