肝脏局灶性结节增生的影像学诊断价值

目的探讨肝脏局灶性结节增生(FNH)的影像学诊断价值。方法回顾性分析经病理证实的肝脏局灶性结节增生18例22个病灶的US、CT和MR影像资料。结果US、CT和MR非造影检出率:US13个,占59.1%(13/22);CT检出16个,占72.7%(16/22);MR显示全部病灶,占100%(22/22)。US、CT和MR造影检出率:US共检出17个,占77.3%(17/22);CT共检出19个,占86.4%(19/22);MR全部检出,占100%(22/22)。正确诊断:US27.3%(6/22),CT40.9%(9/22),MR68.2%(15/22)。影像综合正确诊断:90.9%(20/22)。结论影像学综合检查能够正确诊断绝大部分肝脏局灶性结节增生,MRI诊断准确性明显优于CT和US。

Imaging Diagnostic Value of Focal Nodular Hyperplasia of the Liver

Objective To debate the imaging diagnostic value of focal nodular hyperplasia of the liver.Methods We retrospective analyzed the imaging data of US CT and MR of 22 focal area from 18 patients with hepatic focal nodular hyperplasia which has been testified by pathology.Results US,CT and MR sensitivity rates of none-enhancement pattern are 59.10%(13/22),72.7%(16/22),100%(22/22),respectively.US,CT and MR sensitivity rates of enhancement pattern are 77.3%(17/22),86.4%(19/22),100%(22/22).Correct diagnosis:US 27.3%(6/22),CT 40.9%(9/22),MR 68.2%(15/22).The comprehensive correct diagnosis rate is 90.9%(20/22).Conclusion The imaging comprehensive examination can diagnose most of FNH.And the precision of MR diagnosis is superior to CT and US.
