A 58-year-old man was referred for selective internal radiation therapy for locally advanced unresectable hepatocellular carcinoma. Intra-arterial particle perfusion scintigraphy was performed with SPECT/CT following intra-arterial injection of Tc macroaggregated albumin. Angiography demonstrated a hepatic falciform artery, a feeding artery of the ligamentum teres, whereas scintigraphy demonstrated tracer uptake in the mid-anterior abdominal wall. The hepatic falciform artery was subsequently embolized and the repeat angiogram confirmed successful occlusion. Subsequent post-selective internal radiation therapy PET/CT images did not reveal any tracer uptake in the mid-anterior abdominal wall.
一位 58 岁男性因局部晚期不可切除肝细胞癌而被转介行选择性内部放射治疗。在经肝动脉注射 Tc 巨聚合白蛋白后，进行 SPECT/CT 下的动脉内粒子灌注闪烁显像。血管造影显示镰状肝动脉，即镰状韧带上的供血动脉，而闪烁显像显示在中前腹壁有示踪剂摄取。随后对镰状肝动脉进行栓塞，重复血管造影显示成功闭塞。随后的选择性内部放射治疗后 PET/CT 图像未显示中前腹壁有任何示踪剂摄取。
