本文报告16例肝细胞癌CT扫描的经验。除3例外,全部病例均静脉注射尿路对比剂(200-300毫升)前、后的CT扫描。4例快速滴注50毫升60%tothal-amate meglumine 后行快速连续(动力学)扫描。结果:16例中CT 对病变作了正确鉴定和定位者15例。所发现的病变均表现为密度低于周围肝脏的单或多发衰减区。其中8例界限清楚;7例界限不甚清楚。CT 未发现的1例系由于肿瘤与肝密度相同所致。静脉注射对比剂前、后作扫描的13例中,肿瘤及其范围在注射对比剂前的扫描显示较清楚者6例,前、后扫描无差别者5例,仅2例在注射对比剂后的扫描显示更清楚。对比剂增强后常见肿瘤的某些部分
This article reports 16 cases of hepatocellular carcinoma CT scan experience. Except 3 cases, CT scan of all cases before and after intravenous contrast agent (200-300 ml). 4 cases of rapid infusion of 50 ml 60% tothal-amate meglumine rapid continuous (kinetic) scan. Results: 16 cases of CT lesions were correctly identified and located in 15 cases. All lesions were characterized by a single or multiple attenuation zone with a lower density than the surrounding liver. Of which 8 cases clearly defined; 7 cases less clear boundary. One case not found by CT was due to the same tumor and liver density. In 13 cases before and after intravenous injection of contrast agent, the tumor and its range were clearly shown in 6 cases before the contrast agent injection, 5 cases were not differentiated in the anterior and posterior scanning, only 2 cases were after contrast agent injection The scan shows more clearly. Contrast agents enhance certain parts of the tumor
