  2. Fast low angle shot magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Fast_low_angle_shot...

    FLASH was very rapidly adopted commercially. RARE was slower, and echo-planar imaging (EPI) – for technical reasons – took even more time. Echo-planar imaging had been proposed by Mansfield's group in 1977, and the first crude images were shown by Mansfield and Ian Pykett in the same year. Roger Ordidge presented the first movie in 1981.

  3. Cardiac magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Cardiac_magnetic_resonance...

    In 1973, the first simple NMR image was published and the first medical imaging in 1977, entering the clinical arena in the early 1980s. In 1984, NMR medical imaging was renamed MRI. Initial attempts to image the heart were confounded by respiratory and cardiac motion, solved by using cardiac ECG gating, faster scan techniques and breath hold ...

  4. Cardiac imaging - Wikipedia

    en.wikipedia.org/wiki/Cardiac_imaging

    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. [1]

  5. Cardiac magnetic resonance imaging perfusion - Wikipedia

    en.wikipedia.org/wiki/Cardiac_magnetic_resonance...

    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.

  6. Phase contrast magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Phase_Contrast_Magnetic...

    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. MRA is often used to evaluate ...

  7. Myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Myocardial_infarction

    Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.

  8. Magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Magnetic_resonance_imaging

    Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.

  9. Physics of magnetic resonance imaging - Wikipedia

    en.wikipedia.org/wiki/Physics_of_magnetic...

    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 ...
