Gradient- and spin-echo imaging (GRASE) with the multishot acquisition = 3, 5, 7 was performed to generate T2-mapping and to measure myocardial T2-value in a single-breath-hold. ECG-gating, black-blood preparation and 5-multiecho-time acquisition (i.e., 20, 30, 40, 50, and 60 ms) were applied to both SE and GRASE. The GRASE with the multishot acquisition = 3 provided the T2-mapping with few artifacts and the myocardial T2-values comparable to those acquired by SE imaging during the acceptable breath-holding time. The interventricular septal myocardium may be appropriate for the T2-value measurement.
