^*Each shaded group represents data from the same subject obtained from two studies conducted approximately one hour apart. Studies 1, 2, and 9 were acquired using a window shifting scheme with TR of 1000 msec and effective echo spacing 1.96 msec. The rest of the studies were acquired with TR of 2000 msec and echo spacing of 1.2 msec.

^aHigh resolution (2×2×6 mm³) studies. The rest of the studies were acquired with a 64 × 64 matrix.
