WebApr 11, 2024 · Fitting on a voxel by voxel basis allowed us to exclude signals with severe noise effect. If the ROI signal was averaged directly, voxels with severe noise effect might be included, but if the voxel by voxel fitting was carried out first, we could screen out the voxels with bad signal through the fitting index, which was more accurate.
