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.

test cardiac function in the right, or left ventricle. Cardiac ventriculography is a medical imaging test used to determine a person's heart function in the right, or left ventricle . [ 1 ] Cardiac ventriculography involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped.
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
Phase contrast MRI is one of the main techniques for magnetic resonance angiography (MRA). This is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions , aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.
One of the most common forms of heart failure happens when the left heart ventricle (responsible for pumping oxygen-rich blood to the rest of the body) can’t effectively do its job.
By using bSSFP and parallel imaging with multiple coils, frame rates of 5-10 frames per second have been accomplished, allowing for the visualization of cardiac procedures. [11] An MRI linear accelerator (LINAC) can image tumors and organs on-table. MRI-guided radiotherapy (MRgRT) is limited due to high costs and the personnel costs needed for ...
