Figure 1 HDR-¹⁹²Ir (111-370 GBq) driven to the programmed locations. A: In the patient who had undergone left-lobe resection due to cholangiocarcinoma, hilar recurrence with bile duct dilation was shown by portal-phase CT scan (arrow). B: The stricture of bile duct was clearly shown by cholangiography during PTCD (arrow). C: An 8 mm×60 mm SMART stent was deployed across the stricture. D: The applicator and sham source were inserted though a 10 F internal-external drainage catheter. The dose distribution curves were obtained from the TPS (arrow).
