Cardiovascular Magnetic Resonance (CMR) Imaging
CMR imaging is used to assess the structure and function of the heart and primary blood vessels. It can also provide information on myocardial viability following MI, and on images of coronary arteries and atherosclerotic plaque. With pharmacologic stress, CMR imaging can be used to study wall motion abnormalities and left ventricular function. No radiation exposure is involved.13
Due to the generation of strong magnetic fields in CMR imaging, it isn't recommended in certain patients with cochlear implants, metal-containing ocular implants, pacing wires, pacemakers, or other implants that could be hazardous. Image acquisition can also be challenging in the context of arrhythmias and because of the need for extended breath holding.13
This test is considered an applicable imaging service under the Medicare AUC program.9
