Figure 3

Target volumes of the postoperative HGG patient before radiotherapy. (a). The same patient as Figure 1(a). GTV was resection cavity and high perfusion region; CTV1 covered the mm margin and received 60 Gy/30 fx; CTV2 covered the mm margin, and the ependyma involved. (b). The same patient as Figure 1(b). GTV was resection cavity and high perfusion region; CTV1 covered the mm margin and received 60 Gy/30 fx. (c). The same patient as Figure 2(a). GTV was fiber tracts occurring with disruption and/or absence region; CTV1 covered the mm margin and received 60 Gy/30 fx. (d). The same patient as Figure 2(b). GTV was resection cavity; CTV1 covered the mm margin and received 60 Gy/30 fx.
