From: In vivo proton magnetic resonance spectroscopy of breast cancer: a review of the literature
(a) A post-contrast gradient echo (TR/TE = 4.4/1.1 ms) 1.5 T MRI from a 51-year-old woman with invasive ductal carcinoma demonstrating single-voxel 1H magnetic resonance spectroscopy (1H-MRS) voxel positioning. (b) The corresponding water and lipid suppressed single-voxel 1H-MRS spectrum acquired from the voxel, indicating the resonances present. Spectroscopy parameters: PRESS single voxel 15 × 17 × 20 mm, TR/TE = 3,000/125 ms, 128 averages, CHESS water suppression, MEGA/BASING lipid suppression. ppm, parts per million; tCho, total choline-containing resonance.
