摘　　要：目的 :分析小肝细胞癌 (SHCC)的螺旋CT三期增强扫描的表现特征 ,评价各期的应用价值。方法 :搜集 5 3例经手术病理证实的小肝细胞癌病例。术前全部行螺旋CT双期增强扫描 ,其中 2 1例行延迟期增强扫描 ,统计各期病灶检出数 ,观察病灶强化方式 ,计算检出敏感性。结果 :5 3例共发现 5 6个病灶。动脉期检出48个病灶 ,占 85 7% ,其中 46个 ( 73 2 % )有强化呈高密度 ,2个 ( 3 6% )无强化呈低密度 ;门静脉期检出 40个病灶 ,占 71 4% ,3 8个呈相对低密度 ,2个呈高密度。延迟期共对 2 1个病灶进行了扫描 ,17个呈低密度 ,2个呈高密度 ,2个呈等密度。结论 :螺旋CT三期增强扫描是SHCC可靠的检查方法 ,能充分反应小肝癌的血供特点 ,价值很高。Objective: To analyze the manifestation of small hepatocelullar carcinorma(SHCC) in triphasic spiral CT enhanced scan, and to evaluate diagnostic value of hepatic aterial phase(HAP) , portal venous phase(PVP)and delayed phase(DP). Methods: Dual-phase spiral CT scan ware performed in 53 patients with SHCC( <3 cm) ,in which delayed scan were performed in 21 lesions . The sensitivity were calculated and analysed in each phase and the patterns of enhancement were observed. Results: The study showed that the sensitivity in detecting lesions in HAP , PVP were 85.7% , 71.4% respectively. 21 lesions were performed in DP ,17 of them were all hypodensity ,2 lesions were hyperdensity,2 lesions were isodensity. Conclusion: The triphasic enhanced spiral CT was a relieable method to small hepatocellular carcinoma ,it can reflect the blood supply of small hepatocellular carcinoma.
