Short inversion time on delayed-enhancement magnetic resonance improves diagnostic accuracy in recent-onset heart failure
Background Subendocardial LGE is a marker of ischemic aetiology of left ventricular dysfunction, and of viable myocardium. Using a high relaxivity contrast media such as gadobenate dimeglumine, however, little areas of subendocardial LGE can be masked by the high signal of the blood pool. We halved the optimal TI to null the signal of viable myocardium to obtain LGE images with high signal from viable myocardium, intermediate signal from the blood pool, and no signal from LGE areas, thus enhancing the presence of “hidden areas” subendocardial enhancement.
