Late gadolinium enhancement (LGE) and T1 mapping allow infarction and fibrosis to be identified for characterizing cardiomyopathy and assessing viability. [8] Magnetic resonance angiography may be performed with or without contrast medium and is used to assess congenital or acquired abnormalities of the coronary arteries and great vessels. [9]
English: Real-time MRI of a human heart (2-chamber view) at 2.0 mm spatial resolution and 22 ms temporal resolution. The T1-weighted images were acquired with an RF-spoiled radial FLASH CMR sequence (TR/TE = 2.0/1.3 ms, flip angle 8°, 11 spokes) at 2.0 mm resolution, 8 mm section thickness, and 22 ms acquisition time without ECG or respiratory ...
Additional benefits from cardiac MRI include the ability to detect scar within the heart using late gadolinium enhancement, and identify other abnormalities of the heart muscle itself such as infiltration with iron or amyloid protein. [11] Disadvantages of MRI include lengthy protocols and the potential for claustrophobia.
English: Real-time MRI of a human heart (short-axis view) at 1.5 mm spatial resolution and 33 ms temporal resolution. The T1-weighted images were acquired with an RF-spoiled radial FLASH sequence (TR/TE = 2.2/1.4 ms, flip angle 8°, 15 spokes) at 1.5 mm resolution, 8 mm section thickness, and 33 ms acquisition time without ECG or respiratory ...
Gadolinium(III) containing MRI contrast agents (often termed simply "gado" or "gad") are the most commonly used for enhancement of vessels in MR angiography or for brain tumor enhancement associated with the degradation of the blood–brain barrier (BBB). [3] [4] Over 450 million doses have been administered worldwide from 1988 to 2017. [5]

It consists of the organic acid DOTA as a chelating agent, and gadolinium (Gd 3+), and is used in form of the meglumine salt (gadoterate meglumine). [4] [5] The paramagnetic property of gadoteric acid reduces the T1 relaxation time (and to some extent the T2 and T2* relaxation times) in MRI, which is the source of its clinical utility. Because ...
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.
