TABLE II.
Region-of-interest specific PET RMSE values for gray matter in the head of the caudate nucleus (bilaterally), the left insula and the unique PET GBM lesion (a.u). For each combination of PET duration and MR contrast, the reconstruction result closest to the ground truth is depicted bold faced.
