Figure 1: Preoperative treatment planning based on computed tomography-magnetic resonance imaging fusion, (a and b) The green lines represented the needle pathway. The red cylinders on the needle pathway represented the distribution of seeds. The innermost purple circle showed V200. The inner blue circle represented plan target volume. The red circle represented V100 (the percentage of the target volume covered by the prescription dose). The outermost circle represented V50 (the percentage volume of the brain tumor receiving 50% of the prescription dose). The yellow circle showed organs at risk, (c) The dose-volume histogram of preplan calculated by the TPS (treatment planning system). It showed that D90 was 153.2 Gy, V100 was 96.8%, and V200 was 52.5%
