【摘要】：目的：探讨多层螺旋CT肝脏血管成像技术与标本制作新技术的联合应用在肝脏分段中的价值，探讨门静脉与肝静脉的关系，提出合理的肝脏分段方法。材料和方法： 1．实验材料：新鲜人尸体离体肝脏15个，对比剂(优维显300)，铸型剂JF(聚合树脂的一种)，硅胶，发泡剂，油画染料及纺织染料、水粉染料若干，20％福尔马林溶液，15％盐酸溶液，聚酯共聚体P45。设备：16层螺旋CT(Philips AG，Holand)，真空浸渗箱，压力表，排气阀，电动带锯，低温冰箱，聚酯塑料网，，聚酯塑料箱，辅助品(钢化玻璃、PE管、硅胶管、燕尾夹)。 2．临床资料 2005，10～2006，1月间对200余例患者行三期64层螺旋CT(siemens sensation cardiac 64)肝脏扫描，从中选择出肝脏没有明显病变，对肝脏解剖无影响的病例32例，其中8例由于肝静脉或门静脉显影欠佳而被弃用，仅对肝静脉与门静脉均显影良好的24例患者图像进行分段研究。 3．方法： 3．1．人体肝脏门静脉铸型标本的制作

[Abstract]:Objective: to explore the value of combined application of multi-slice spiral CT hepatic angiography and specimen making in liver segmentation, to explore the relationship between portal vein and hepatic vein, and to put forward a reasonable method of liver segmentation. Materials and methods: 1. Experimental materials: 15 fresh human cadaveric livers, contrast agent (Youwei 300), casting agent JF (a kind of polymeric resin), silica gel, foaming agent, oil painting dye and textile dye, water powder dye, 20% formalin solution, 15% hydrochloric acid solution, polyester copolymer P45. Equipment: 16-layer spiral CT (Philips AG,Holand), vacuum infiltration box, pressure gauge, exhaust valve, electric band saw, low temperature refrigerator, polyester plastic net, polyester plastic box, auxiliary products (toughened glass, PE tube, silicone tube, swallow tail clip). 2. More than 200 patients underwent three-stage 64-slice spiral CT (siemens sensation cardiac 64 liver scanning in 2005, 10, 2006 and January. 32 patients with no obvious liver lesions and no effect on liver anatomy were selected. Among them, 8 patients were abandoned because of poor development of hepatic vein or portal vein. Only 24 patients with good development of hepatic vein and portal vein were studied. 3. Methods: 3.1. Preparation of cast specimens of portal vein of human live
