Computation of MTR in amygdala and hippocampus.>>A, Fifty transverse sections (3 mm) covering the whole brain and angled along the temporal plane by use of a pair of 3D gradient-echo acquisitions, without (No Sat) and with (Sat) MT saturation pulses, respectively, were obtained using 35/10/1 and a flip angle of 40 degrees. Semisolid spin saturation was achieved using 1.2-ms on-resonance 121 binomial pulses (|B1| = 19 μT) placed just before each section selective excitation.
B, Percentage difference (100 × [No Sat—Sat]/No Sat) MT images were calculated after thresholding above the noise background.
C, Amygdala (white arrow) and hippocampus (black arrow) were outlined on volumetric T1-weighted 1-mm isotropic voxel acquisition.
D, Volumetric T1-weighted images, with outlined mesial temporal structures, and MT images were coregistered. The MTR of amygdalae, hippocampi, and asymmetry index were computed.
