MRI与增强CT对肝癌的诊断价值

Diagnostic Value of MRI and Enhanced CT for Liver Cancer

目的探讨与分析磁共振成像(MRI)与增强CT对肝癌的诊断价值。方法选择72例肝癌患者(肝癌组)与72例肝硬化患者(肝硬化组),所有患者都给予MRI与增强CT检查,记录诊断效果。结果肝癌组的HAF、HPF与HPI值都显著低于肝硬化组(P<0.05)。肝癌组的MRI的峰值时间低于对照组(P<0.05),信号增强比率高于对照组(P<0.05)。在144例患者中,MRI与增强CT诊断为肝癌71例与70例,诊断的敏感性分别为98.6%和95.8%,特异性分别为100.0%和98.6%。结论MRI与增强CT对肝癌的诊断均有其自身的特点及优势,在具体应用时要结合患者临床特征及自身情况进行综合考虑。

Objective To investigate and analyze the diagnostic value of magnetic resonance imaging(MRI)and enhanced CT in liver cancer.Methods 72 patients with liver cancer(hepatocarcinoma)and 72 patients with cirrhosis(cirrhosis)were enrolled.All patients were underwent MRI and enhanced CT examination,recorded the diagnosis values.Results The HAF,HPF and HPI values of the liver cancer group were significantly lower than those of the liver cirrhosis group(P<0.05).The peak time of MRI in the liver cancer group were lower than that of the control group(P<0.05),and the signal enhancement rate were higher than that of the control group(P<0.05).In the the 144 patients,MRI and enhanced CT were diagnosed as 71 patients and 70 patients of liver cancer,the diagnostic sensitivities were 98.6%and 95.8%,respectively,and the specificities were 100.0%and 98.6%,respectively.Conclusion MRI and enhanced CT have their own characteristics and advantages in the diagnosis of liver cancer.In the specific application,the clinical characteristics and their own conditions should be considered comprehensively.
