The CT-guided radioactive iodine-125 seed implantation procedure and dose-volume histograms of gross tumor volume

Figure (a-c) showed the preoperative treatment plan including the planned needle locations, seed distribution, and target volume dose in a case of squamous cell carcinoma of the tongue with cervical lymph node metastasis. The green needles and red seeds were the simulated needles and seeds in the brachytherapy treatment planning system. Figure (d-f) showed the actual locations of the needles before the implanting of seeds during operation. Figure (g-i) showed the actual distribution of seeds and the dose in target volume after seed implantation. Figure (j-k) showed the dose-volume histograms of gross tumor volume preoperation and postoperation
