摘　　要：目的探讨多层螺旋CT(MSCT)不同时相扫描对多中心性肝细胞癌的诊断价值。方法选取64例多中心性肝细胞癌患者,均于病理检查前接受MSCT检查,以病理诊断结果为金标准,评估MSCT不同时相扫描对肝癌病灶的检出率;比较正常肝脏组织与肝癌病灶MSCT不同时相扫描的CT值。结果病理检查结果显示,64例多中心性肝细胞癌患者共96个病灶,MSCT检查共检出94个病灶,检出率为97.92%。MSCT增强扫描动脉期检出88个病灶,检出率为91.67%,高于门脉期的78.12%和延迟期的81.25%,差异均有统计学意义(P﹤0.05)。正常肝脏组织CT平扫、动脉期CT值均明显低于肝癌病灶,门脉期、延迟期CT值均明显高于肝癌病灶,差异均有统计学意义(P﹤0.01)。多中心性肝细胞癌CT平扫可见肝脏体积增大,形态欠规整;增强扫描呈快进快出模式,动脉期可见轻度不均匀强化,门脉期强化程度逐渐下降,延迟期呈低密度影。结论MSCT增强扫描可清晰地显示多中心性肝细胞癌的强化特征,提高早期检出率。Objective To analyze the diagnostic value of multi-slice spiral CT(MSCT)in different phase scans for multicenter hepatocellular carcinoma.Method A total of 64 patients with multicenter hepatocellular carcinoma were selected,all of them underwent MSCT examination before pathological examination.Using pathological diagnosis results as the gold standard,the detection rates of liver cancer lesions by MSCT at different time phases were evaluated.The CT value on MSCT different time phases were compared between the normal liver tissues and liver cancer lesions.Result The pathological examination results showed that there were 96 lesions in 64 patients with multicenter hepatocellular carcinoma,and MSCT examination detected a total of 94 liver cancer lesions,with detection rate of 97.92%.MSCT enhanced scan detected 88 liver cancer lesions in the arterial phase,with detection rate of 91.67%,which was higher than 78.12%in the portal phase and 81.25%in the delayed phase,the differences were statistically significant(P<0.05).The CT values of normal liver tissues on CT plain scan and arterial phase were lower than those of liver cancer lesions,while the CT values in portal phase and delayed phase were higher than those of liver cancer lesions,the differences were statistically significant(P<0.01).CT plain scan showed that the multicenter hepatocellular carcinoma was enlarged in size and unregular in shape,the enhanced scan showed a fast-in and fast-out mode,with mild uneven enhancement visible in the arterial phase,the portal phase enhanced gradually decreased,and the delayed phase showed low density.Conclusion MSCT enhanced scann can clearly display the enhanced characteristics of multicenter hepatocellular carcinoma,and improve the early detection rate.
