A
modified single-shot turbo spin echo (HASTE) sequence was used to generate
quantitative T2 maps in a single breath-hold per slice. Whole heart T2 maps (3
short-axis slices) for a population of healthy subjects show regional
variations in T2, with increased values at the apex and decreased
values on the lateral wall of the basal slice. T2 maps for a patient with acute
myocardial infarction shows elevated T2 in inferoseptal regions
overlapping with occluded artery perfusion territory and regions of late
gadolinium enhancement. 11 patients
showed abnormal (mean + 3SD) T2 in 33% of regions.
