Interventional magnetic resonance imaging, also interventional MRI or IMRI, is the use of magnetic resonance imaging (MRI) to do interventional radiology procedures.. Because of the lack of harmful effects on the patient and the operator, MR is well suited for "interventional radiology", where the images produced by an MRI scanner are used to guide a minimally-invasive procedure ...
Cardiac magnetic resonance imaging (cardiac MRI, CMR), also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. [2]
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.

In November 1992, a patient with an undisclosed cerebral aneurysm clip was reported to have died shortly after an MRI exam. [7] Several deaths have been reported in patients with pacemakers who have undergone MRI scanning without appropriate precautions. [8] Increasingly, MR-conditional pacemakers are available for selected patients. [9]
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.
A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [3] thus regulating the function of the electrical conduction system of the heart.
Pacemaker syndrome is a condition that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation. [1] [2] It is an iatrogenic disease—an adverse effect resulting from medical treatment—that is often underdiagnosed.
This application is particularly helpful when a 3D image of the tissue is needed during surgery. [11] It requires an in-room display for the physician to use during the procedure as well as the use of MRI-safe surgical tools. These include ceramic, plastic, or titanium, which is a paramagnetic metal. By using bSSFP and parallel imaging with ...
