A 47-year-old male patient with cholangiocarcinoma received SEMS insertion plus CT-guided percutaneous 125I seed implantation. A Cholangiography showed the obstruction of the common bile duct. B Cholangiography showed an 8×80 mm self-expandable metallic biliary stent insertion. C Computed tomography showed the mass of malignancy. D Computed tomography showed the image of the percutaneous 125I seed implantation process. E Computed tomography showed the seeds’ distribution after 125I seed implantation. F Three-dimensional reconstructed image of the implanted seeds. G Dose distribution of the seeds on TPS. H Dose-volume histogram calculated after CT-guided percutaneous 125I seed implantation
