There is a growing interest for applying T2
mapping for non-invasively tracking inflammatory changes in patients with neuromuscular
diseases. T2 has been traditionally quantified using multi-echo spin-echo (MESE)
sequences with known problems related to the refocusing pulses in presence of
B1-inhomogeneity and slice profiles effects. The present work proposes the
combination of an adiabatic T2-preparation with 3D TSE for B1-insenstive T2
mapping. The proposed method is compared with 2D-MESE and 3D-MESE, in terms of
reproducibility on T2 quantification and sensitivity to B1 effects, in the
thigh musculature of ten healthy subjects.
