## Abstract __T__~2~βweighted MRI of edema in acute myocardial infarction (MI) provides a means of differentiating acute and chronic MI, and assessing the area at risk of infarction. Conventional __T__~2~βweighted imaging of edema uses a turbo spinβecho (TSE) readout with darkβblood preparation. Cl
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
## Abstract ## Purpose To investigate a T1 and T2 preparation pulse sequence to evaluate microvascular obstruction (MO) in a porcine model of reperfused acute myocardial infarction (AMI). ## Materials and Methods A total of 14 pigs with reperfused AMI underwent MRI examinations at baseline and t
