The preoperative diagnosis of a focal nodular hyperplasia (FNH) is of special interest as in case of non-malignancy of this tumor no extirpation has to be carried out. 86 patients - 19 of them suffered from FNH - have been examined by 3 phasecholescintigraphy. There were no false positive findings (specifity 100 per cent). 2 out of 23 examined FNH were not recognized as such (sensitivity 87 per cent) because the tumor had been changed regressive largely. Cholescintigraphy is an excellent method to prove FNH not bothering the patient too much. Cholescintigraphy should be the first measure of differential diagnostic clarification whenever a benign tumor is suspected.
局灶性结节性增生（FNH）的术前诊断具有特殊意义，因为如果该肿瘤为非恶性，则无需进行切除。86例患者接受了三相胆系闪烁造影检查，其中19例患有FNH。没有假阳性结果（特异性为100%）。在23例接受检查的FNH中，有2例未被识别出来（敏感性为87%），因为肿瘤已大部分发生退行性改变。胆系闪烁造影是证实FNH的一种极佳方法，对患者的干扰较小。每当怀疑为良性肿瘤时，胆系闪烁造影都应作为鉴别诊断的首要措施。
