摘　　要：目的:探索多排螺旋CT肝脏多期增强扫描对鉴别肝脏肿瘤的意义。方法:选择141例经病理确诊为肝脏肿瘤并行多排螺旋CT平扫及增强扫描的患者资料,观察CT平扫及增强扫描诊断肝脏肿瘤的不同表现及结果,以病理检查为金标准,观察CT增强扫描诊断肝脏肿瘤的敏感性。结果:CT平扫共发现病灶93例;多期增强扫描中动脉期发现141例,门静脉期发现112例,延时期发现108例。平扫与动脉期、门静脉期及延迟期相比,病灶检出率明显较低;在CT增强扫描下,大部分病灶呈典型征象,可以确诊。多排螺旋CT肝脏多期增强扫描诊断血管瘤的灵敏度为88.9%,脓肿的灵敏度为71.4%,局灶结节性增生的灵敏度为83.3%,原发性肝癌的灵敏度为81.6%,肝转移瘤灵敏度为97.8%,总准确率为88.7%。结论:多排螺旋CT肝脏多期增强扫描能较准确地鉴别肝脏肿瘤病变,有助于临床进一步治疗。Objective： To explore the significance of multiple detector spiral CT multi-phase enhanced scan in differentiating liver tumors. Methods： A total of 141 patients, during from March 2011 to May 2015 in our hospital, pathologically diagnosed as liver tumors wereselected to undergo multiple detector spiral CT multi-phase enhanced scan. The different performances and results in CT plain and enhanced scan for diagnosing liver cancer were observed and the sensitivity of CT multi-phase enhanced scan was analyzed. Results： 93 cases were found in CT plain scan; 141 cases were found in the arterial phase, 112 cases were found in portal venous phase and 108 cases were found in extension period in CT multi-phase enhanced scan. The lesion detection rate of CT plain scan was significantly lower than whichever of CT multi-phase enhanced scan（P0.05）; under CT multi-phase enhanced scan, the majority of lesions were typical imaging and could be diagnosed. Using CT multi-phase enhanced scan, the sensitivity of hemangiomas was 88.9%, abscess was 71.4%, focal nodular hyperplasia was 83.3%, primary liver cancer was 81.6%, and liver metastases was 97.8%; the total accuracy was 88.7%. Conclusion： The multiple detector spiral CT multi-phase enhanced scan can accurately identify liver tumor lesion stages, and it can contribute to further clinical treatment.
