Non-contrast T1-mapping using the novel ShMOLLI (Shortened Modified Look-Locker Inversion Recovery) sequence detects acute myocardial edema with high diagnostic accuracy.
Patients with acute myocarditis and healthy volunteers were studied to assess the ability of T2 mapping to detect myocardial edema. The T2 maps detected global and regional edema in patients. T2 mapping may be an alternative to STIR images for detecting myocardial edema in patients with acute myocar
Magnetic resonance images were obtained from 32 patients with acute myocardial infarction, using a four-echo technique (echo time (TE) = 30, 60, 90, and 120 ms) pregadolinium(Gd)-DTPA injection and a TE = 30 ms sequence pre- and post-Gd-DTPA. Intensity ratios of infarcted and normal myocardium were
