摘　　要：目的探讨1. 5T核磁共振(MRI)动态增强扫描在肝癌分期评估中的临床应用。方法选择86例肝癌患者作为研究对象,记录所有患者的常规1. 5T MRI与动态增强扫描特征,并与病理情况进行对比分析。结果 MRI诊断临床分期为T1期51例,T2期21例,T3期8例,T4期6例。MRI分期与病理分期有较好的一致性(k=0. 892),诊断准确率为96. 5%。常规MRI特征为T1WI呈低信号49例,病灶边缘强化不规则,程度不等;动态增强扫描判断为Ⅰ型36例,Ⅱ型34例,Ⅲ型10例,Ⅳ型6例。MRI评价肝癌可切除性的敏感性、特异性、准确性分别为88. 9%、100. 0%和95. 3%。结论 1. 5T MRI动态增强扫描在肝癌中的应用有助于指导临床病理分期诊断与可切除手术治疗,有很好的应用价值。Objective To explore the clinical application values of dynamic enhanced scanning1. 5 T magnetic resonance imaging( MRI) in the staging of hepatocellular carcinoma. Methods 86 patients with hepatocellular carcinoma treated were selected. The characteristics of the routine 1. 5 T MRI and dynamic enhanced scanning were recorded and compared with the pathological conditions. Results The clinical stages of MRI were 51 cases in T1 stage,21 cases in T2 stage,8 cases in T3 stage,6 cases in T4 stage,the MRI stage were in good agreement with the pathological stage( k = 0. 892),and the diagnostic accuracy were96. 5%. The routine MRI were characterized by 49 cases of low signal T1 WI,irregular edge enhancement and unequal degree,and there were 36 cases of type Ⅰ,34 cases of type Ⅱ,10 cases of type Ⅲ and 6 cases of type Ⅳ by dynamic enhanced scanning.The sensitivity,specificity and accuracy of MRI in evaluating resectability of hepatocellular carcinoma were 88. 9%,100. 0% and95. 3% respectively. Conclusion The application of 1. 5 T MRI dynamic enhanced scanning in hepatocellular carcinoma is helpful in the diagnosis of clinic staging and the treatment of resectability,and so it has good application value.
