摘要
目的探讨肝脏局灶性结节增生(focal nodular hyperplasia,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。
Objective: To assess the imaging diagnostic value of focal nodular hyperplasia of the liver. Methods: US, CT and MR imaging data of 18 patients (22 focal) with hepatic focal nodular hyperplasia which are proved by pathology were retrospectively analyzed. 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 FNH. And the precision of MR diagnosis is superior to CT and US.
