Two-Site Reproducibility of Cerebellar and Brainstem Neurochemical Profiles With Short-Echo, Single-Voxel MRS at 3T

摘要

PurposeTo determine whether neurochemical concentrations obtained at two MRI sites using clinical 3T scanners can be pooled when a highly optimized, nonvendor short-echo, single-voxel proton MRS pulse sequence is used in conjunction with identical calibration and quantification procedures.
