CT及MRI检查对肝脏局灶性结节增生病灶的诊断价值

Diagnostic Value of CT and MRI Examination for Lesions of Local Nodular Hyperplasia in Liver

目的:探讨肝脏局灶性结节增生(FNH)行CT与MRI检查的诊断价值。方法:选取我院2010年至2013年收治的FNH患者32例,对患者CT与MRI影像学检验的结果分析。结果:32例患者共发现病灶37个,为圆形或椭圆形,31个病灶边界均较为清晰。MRI增强扫描,三期信号特点与CT增强扫描三期信号特点相似,病灶ADC与正常肝脏ADC相比无显著差异。结论:CT与MRI平扫与增强扫描较为全面,而两种影像学检查方式征象均有特征性,MRI较为明显,两种方式联合诊断具有较高的临床价值。

Objective： To observe the diagnostic value of CT and MRI examination for local nodular hyperplasia in liver. Methods： 32 cases with FNH treated in our hospital from 2010 to 2013 were selected. And the image test results of CT and MRT were analyzed. Results： There were 37 lesions for 32 cases,which were circular or oval. The edge of 31 lesions was clear. The characteristics of three-stage signals for MRI enhancement scan were similar to that of CT enhancement scan. There was no evident difference between lesion ADC and normal liver ADC. Conclusion： CT and MRI plain scan and enhancement scan are comprehensive,but the signs of two imaging examination modes are characteristic. And MRT is more evident. The combination of both modes for diagnosis has high clinical value.
