Figure 1.

A scheme diagram of the proposed pulse sequence. The pulse sequence starts with a 90 degree RF pulse followed with crusher gradients to reset net magnetization. A long T1 recovery time is followed to allow longitudinal signal recovery before T1rho-prep. Spectral attenuated inversion recovery (SPAIR) and gradient reversal approach are used for fat suppression. A RF pulse cluster which has simultaneous compensation of B1 RF and B0 field inhomogeneity is used for T1rho-prep. Data is acquired using single shot fast/turbo spin echo (SSFSE/SSTSE) approach. The SSFSE acquisition is combined with double inversion recovery to achieve black blood effect. A phase correction module is used to maintain CPMG condition for SSFSE acquisition.
