CMR T2-mapping is needed to assess myocardial edema after such events as acute myocardial infarction, myocarditis and tako-tsubo cardiomyopathy. Many T2mapping sequences have been developed, but most suffer from design shortcuts that degrade their accuracy, consistency and prognostic value. T2maps from four-point T2 curve-fits at end-systole (ES) would have maximum wall thickness and fewest artifacts for better prognostic value. We present a new sequence that produces accurate four-point T2maps at ES within a 24-second breathhold at 3T. This sequence was tested on phantoms and healthy human volunteers to present superior results.
