肝脏局造性结节增生的MRI诊断价值分析

Analysis of diagnosis value of MRI on focal nodular hyperplasia of the liver

目的探讨MRI在肝脏局灶性结节增生(FNH)中的诊断价值。方法回顾性分析FNH患者12例的MRI和CT影像学表现。结果 MRI对FNH病灶的定性率及中央瘢痕、假包膜的显像率均高于CT,差异有统计学意义(P<0.05)。但MRI和CT对FNH病灶供血动脉的显像率比较差异无统计学意义(P>0.05)。结论 MRI平扫及动态增强对FNH的诊断具有较明显的优势和较高的价值。

Objective To evaluate the diagnosis value of MRI on focal nodular hyperplasia（FNH） of the liver.Methods The image manifestations of 12 patients with FNH were analyzed retrospectively.Results The qualitative rate and central scar,psuedocapsule developing rate of MRI on FNH were higher than that of CT,and the differences were statistically significant（P〈0.05）.But there was no significant difference of the developing rate of the supplying arteries of FNH lesions between MRI and CT（P〈0.05）.Conclusion The MRI plain and dynamic enhanced scan has clear superiority and great value in the diagnosis of FNH.
