For each specimen, imaging was performed at both 1.5T on a Signa HDxt scanner and a 3T Discovery MR 750 scanner (GE Healthcare, Waukesha, WI). using 8 channel transmit-receive knee coils (In-Vivo Coorporation, Gainesville, FL). We used MAVRIC-SL that combines the advantages of MAVRIC’s efficient spectral-spatial acquisition with SEMAC’s slab-selective properties.(5 (link), 6 (link), 20 (link)) and compared to conventional fast spin echo (FSE) sequences. The MRI protocol included a proton density (PD)-weighted 2D fast spin echo (FSE) sequence, a T2-weighted 2D FSE sequence, a short T1 inversion recovery (STIR) fat suppressed sequence, PD-weighted 3D MAVRIC-SL sequence, and 3D MAVRIC-SL with STIR fat suppression. For STIR fat suppression, the inversion time was 150 ms for 1.5T and 170 ms for 3T. For MAVRIC-SL, 24 spectral bins were acquired with 1kHz frequency offset per bin, and an echo train length of 24, a slice thickness of 3 mm, and field of view of 21 cm were used for imaging parameters. For FSE, large readout bandwidths (+/−62.5 or +/−125 kHz) were used in order to minimize the expected artifacts ensuring a fair comparison. Table 1 shows the detailed sequence parameters.
