摘　　要：目的:评价螺旋CT三期扫描,使用370mg I/ml高浓度碘对比剂联合低剂量扫描技术,结合多平面重建在肝脏占位鉴别诊断中的价值。材料与方法:选择肝占位40例,使用碘普罗胺370对比剂(碘浓度370mg I/ml,对比剂剂量为85ml)、管电压100KV,应用16排西门子螺旋CT三期增强扫描,部分行多平面重建,以观察肝占位三期强化的方式和特征。结果:40例肝占位(16例为原发性肝ca,10例肝血管瘤,5例肝转移瘤,1例肝腺癌,6例肝硬化结节,2例肝脓疡),螺旋CT三期扫描是肝占位鉴别诊断的最佳方式,能充分反映病灶的血供特征。结论:16排CT三期扫描及后处理技术联合低剂量高浓度碘对比剂可鉴别不同肝占位的病变特征及其与周围组织的关系,可以获得满意的肝脏血管成像图像,同时降低辐射剂量和对比剂的不良反应及减少对比剂的用量。Purpose ： Evaluation of three periods of spiral CT scanning, using mgi / 370 ml high concentrations of io- dine contrast agent in combination with low dose of scanning technology, combined with multiplanar reconstruction in liver placeholder value in differential diagnosis. Materials and Methods： Choose 40 cases in the liver, the use of iodine 370 ordi- nary amine contrast agent （iodine concentration mgi / 370 ml, contrast medium doses of 85 ml）, tube voltage 100 kv, the ap- plication of 16 row of three periods of Siemens spiral CT enhanced scan, part of the line of muhiplanar reconstruction, to ob- serve the liver of the third phase of strengthening methods and characteristics. Results ： 40 cases of the liver （ 16 eases of pri- mary liver cancer, 10 cases of liver hemangioma, 5 cases of liver metastases, 1 case of hepatic carcinoma, 6 cases of liver cir- rhosis nodules, 2 cases of hepatic abscess） , three phase spiral CT scanning is the best way for the liver differential diagnosis, can fully reflect the characteristics of the flow of blood to the lesions. Conclusion ： 16 row of three periods of CT scanning and post-processing technology in combination with low dose of high concentration of iodine contrast agent can identify the different characteristics of lesions of the liver and relationship with the surrounding tissue, can obtain satisfactory liver vascular imaging image, at the same time reduce the radiation dose and adverse reaction of contrast medium and reducing the amount of contrast medium.
