Fig. 3. Gamma Knife radiosurgery (GKS) treatment planning covering the amygdala, hippocampal head and body, most of the parahippocampal gyrus, and the entorhinal cortex. (A) axial view, (B) coronal view, (C) sagittal view, and (D) 3-dimensional view. The target region (blue color) of 8.8 cm3 volume received marginal dose (yellow color) of total 24 Gy in 3 fractionations in 3 consecutive days with a dose of 8 Gy at the 50% isodose line (Min. dose, 4.1 Gy; Max. dose, 16.1 Gy; Mean dose, 11.1±2.0 Gy). Dose delivered to optic tract (red color) were on mean 3.0±1.7 Gy (Min. Dose, 0.9 Gy; Max. Dose, 7.5 Gy).
