    Cardiac magnetic resonance imaging perfusion (cardiac MRI perfusion, CMRI perfusion), also known as stress CMR perfusion, [1] is a clinical magnetic resonance imaging test performed on patients with known or suspected coronary artery disease to determine if there are perfusion defects in the myocardium of the left ventricle that are caused by narrowing of one or more of the coronary arteries.

    During the last 150 years, thousands of papers focusing on the effects or side effects of magnetic or radiofrequency fields have been published. They can be categorized as incidental and physiological. [2] Contraindications to MRI include most cochlear implants and cardiac pacemakers, shrapnel and metallic foreign bodies in the eyes.

    en.wikipedia.org/wiki/Cardiac_stress_test

    A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.

    However, greater capital costs and effects of off-resonance artefact on image quality mean that many studies are routinely performed at 1.5T. [29] Imaging at 7T field strength is a growing area of research, but is not widely available. [30] Current manufacturers of cardiac-capable MRI scanners include Philips, Siemens, Hitachi, Toshiba, GE.

    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.

    Stress test: A stress test, also called an exercise stress test, provides information about how well the heart works during physical activity. It usually involves walking on a treadmill or riding a stationary bike while heart rhythm, blood pressure, and breathing are monitored. Cardiac computerized tomography (CT) or magnetic resonance imaging ...
