(A) High-resolution axial 11.7-T magnetic resonance (MR) image of the tibia and fibula of a male Sprague-Dawley rat obtained ex vivo (gradient echo; TR/TE, 500 ms/5.07 ms; signal averages, 4; field of view [FOV], 1.7 cm × 1.7 cm; matrix, 256 × 256, 0.066 mm × 0.066 mm; slice thickness, 0.5 mm). Chemical shift artifact at fat-muscle interfaces can be appreciated. (B) High-resolution axial 11.7-T MR image of the tibia and fibula of a male Sprague-Dawley rat obtained ex vivo (spin echo; TR/TE, 2500 ms/8.0 ms; signal averages, 2; FOV, 1.6 cm × 1.6 cm; matrix, 512 × 512, 0.031 mm × 0.031 mm; slice thickness, 0.5 mm). The difference in contrast between bone marrow, muscle, and fat at 11.7 T can be appreciated.
