Table 1.
Mean R2* ± SD (s−1) in each marmoset, as well as the intermarmoset average (avg), calculated for different ROIs: GM, mGM, and selected WM regions (AC, GCC, SCC, WM1, and WM2). Values were obtained from MGRE data collected in the sphinx position. For one animal (#5), MGRE data were averaged four times (# avgs.=4) before R2* mapping. Abbreviations: GM, gray matter; mGM, myelinated gray matter; AC, anterior commissure; GCC, genu of the corpus callosum; SCC, splenium of the corpus callosum; WM, white matter.
