Short-echo-time magnitude image derived from quantitative susceptibility mapping could resemble neuromelanin-sensitive MRI image in substantia nigra

摘要

The segmentation of SNhyper regions of interest (ROI) on setMag and NM-MRI images of a representative subject. A zoomed in view of midbrain area on the setMag and NM-MRI images are shown in a and c, respectively. The corresponding left and right SNhyper regions of interest (ROI) segmented by rater 1 (red), rater 2 (green) and their consensual voxels (yellow) are shown in b and d
