The effects of voxel localization and time of echo on the diagnostic accuracy of cystic brain tumors in 3 tesla magnetic resonance spectroscopy https://adir.tums.ac.ir/article/The-effects-of-voxel-localization-and-time-of-echo-on-the-diagnostic-accuracy-of-cystic-brain-tumors-in-3-tesla-magnetic-resonance-spectroscopy choline (Cho), N acetyl aspartate (NAA) and creatinine (Cr). Moreover, the role of voxel localization on the diagnosis of the neoplastic nature of the lesions is assessed through comparing the abovementioned metabolite ratios in the rim and center of each...
