Summary of performance of the methods in 55 patients (105 exams). The average SNRs of three main metabolites and their ratios in normal-appearing white matter from 55 patients with gliomas are shown with different color bars representing each technique. SNR corrections were made for variation in Tacq, TR and spatial resolution for all exams. Although the RWvoxel method produced the best overall SNR, all methods produced consistent metabolite ratios.
