a: MRS of the ipsilateral hippocampus of a KA animal showed that NAA peaks at 3.64, Cho peaks at 3.13, and Cr peaks at 3.67 at 3.0 T; b: MRS of contralateral hippocampus of a KA animal showed that NAA peaks at 4.10, Cho peaks at 2.73, and Cr peaks at 2.60 at 3.0 T. c: MRS of right hippocampus of a control animal showed that NAA peaks at 4.43, Cho peaks at 2.88, and Cr peaks at 3.32 at 3.0 T.
