Quantitative T
2
mapping
allows non-invasive assessment of myocardial
inflammation/edema. In T
2
mapping
sequences, rest-cycles are needed between different T
2
weighted
images to allow full magnetization recovery, which
results in reduced scan time efficiency. In such
sequence, multi-segment acquisition is difficult to be
employed due to the long scan time. Recently,
free-breathing multi-slice myocardial T
2
mapping
sequence was proposed to increase scan time efficiency
by combining a slice-selective T
2
prep pulse
and interleaved slice acquisition. In this study, we
sought to further extend the multi-slice T
2
mapping
sequence to allow segmented acquisition to achieve
higher in-plane spatial resolution within acceptable
scan time.
