This work presents a new
method to achieve fast T1 and T2 mapping in 1H-MRSI
experiments using SPICE without water suppression. With a novel data acquisition
and processing scheme, T1 and T2 maps at 1.0×1.0×2.0 mm3 were obtained successfully in one-minute extra scan time.

method. High-resolution T1, T2, PD maps at 1.0×1.0×2.0 mm3
resolution and metabolite distributions (NAA, Cr, Cho, …) maps at 2.0×3.0×3.0
mm3 resolution were obtained in a total 8-minute scan.
