Plain radiography and CT of the abdomen were reviewed in four patients who had undergone angiography with thorium dioxide (Thorotrast). In three patients CT showed irregularly scattered focal punctate collections of Thorotrast in the liver parenchyma, predominantly in the subcapsular zone, associated with areas of low or nonhomogeneous attenuation. These areas of low attenuation were identified on microscopic studies as sites of hepatic fibrosis or neoplasia. Computed tomography identified intrahepatic Thorotrast deposits more definitively than plain radiography.
对4例曾接受二氧化钍（钍胶体）血管造影的患者的腹部平片和CT进行了回顾。3例患者的CT显示，肝实质内有不规则散在的局灶性点状二氧化钍聚集，主要位于包膜下区，伴有低密度或不均匀衰减区域。这些低密度区域在显微镜检查中被确定为肝纤维化或肿瘤形成部位。计算机断层扫描比腹部平片更能明确地识别肝内二氧化钍沉积。
