MSCT平扫联合三期动态增强扫描诊断肝细胞癌的价值分析

Analysis on the Value of MSCT Plain Scan Combined with Three-Phase Dynamic Enhanced Scan in the Diagnosis of Hepatocellular Carcinoma

目的分析多层螺旋CT(MSCT)平扫联合三期动态增强扫描诊断肝细胞癌(HCC)的价值。方法回顾性分析85例HCC患者的临床资料,所有患者均接受MSCT平扫和三期动态增强扫描,比较MSCT平扫与三期动态增强扫描的病灶检出率,分析HCC病灶的密度分布情况。结果动脉期、延迟期的病灶检出率高于平扫和门静脉期(P<0.05);联合诊断的病灶检出率为100.00%,高于平扫的65.26%(P<0.05)。HCC病灶在动脉期主要表现为高密度影,在门静脉期和延迟期主要表现为低密度影。结论MSCT平扫联合三期动态增强扫描可显著提升HCC患者的病灶检出率,尤其是对微小病灶的检出。

Objective To analyze the value of multi-slice spiral CT(MSCT)plain scan combined with three-phase dynamic enhanced scan in the diagnosis of hepatocellular carcinoma(HCC).Methods The clinical data of 85 patients with HCC were retrospectively analyzed.All patients underwent MSCT plain scan and three-phase dynamic enhanced scan.The lesion detection rates of MSCT plain scan and three-phase dynamic enhanced scan were compared,and the density distribution of HCC lesions was analyzed.Results The lesion detection rates in arterial phase and delayed phase were higher than those in plain scan and portal vein phase(P<0.05);The lesion detection rate of combined diagnosis was 100.00%,higher than 65.26% of plain scan(P<0.05).HCC lesions mainly showed high density in arterial phase and low density in portal venous phase and delayed phase.Conclusions MSCT plain scan combined with three-phase dynamic enhanced scan can significantly improve the detection rate of HCC,especially for small lesions.
