摘　　要：目的探讨64层螺旋CT薄层扫描在原发性肝癌诊断中的应用价值。方法回顾性分析32例经临床及手术病理证实的原发性肝癌平扫及增强三期的影像表现。结果 77.8%的癌灶在肝动脉期呈现高密度强化表现,充分说明螺旋CT扫描可反映肝癌的血供特点,门脉期有41.7%的病灶呈现等密度,63.9%病灶呈现低密度影像,也反映了肝细胞癌"速升速降"的增强变化特点,可作为诊断原发性肝癌最有价值的征象。结论螺旋薄层扫描可充分反映原发性肝癌的特征,对肝癌的检出和定性准确率的提高有重要价值。Objective Thin layer scan for the 64-slice spiral CT in primary liver cancer diagnosis application.Method Retrospective analysis of 32 cases of clinical and surgical pathology of primary liver cancer plain and enhanced the performance of three images.Results 77.8% of the foci in the hepatic arterial phase showed enhanced performance of high-density,fully illustrated spiral CT scan may reflect the liver＇s blood supply,portal venous phase with 41.7% of lesions showed equal density,63.9% of lesions showed low-density images,but also reflects hepatocellular carcinoma ＂downhill fast rise,＂ the enhanced changes in the characteristics of primary liver cancer as the most valuable diagnostic signs.Conclusion Thin layer scan spiral primary liver cancer can be adequately reflect the characteristics of the detection and characterization of liver cancer to improve the accuracy of significant value.
