摘 要:目的 探讨超声对肝脏局灶性结节性增生(FNH)的诊断价值。方法 对10例共10个手术及病理证实的FNH进行超声分析。结果 FNH在常规B超上多表现为低回声及均匀的实质回声,偶见低回声的星状疤痕,但总体上缺乏较特异的声像图表现;而彩色多普勒可显示一粗大的彩色血流伸入病灶中央并分支,显示率为70%,部分呈轮辐状排列(20%),有一定的特征。Objective To evaluate the value of diagnosing for focal nodular hyperplasia.Methods Ten patients with pathologically proven FNH of the liver were examined by conventional ultrasound and color Doppler ultrasound.Results In these patients,the hypoechoic pattern with homogeneous solid lesions was mostly displayed on conventional ultrasound,and the central stellate scar was found in one patient.Therefore,no specific sonography could be identified.A color blood flow with arterial spectrum was detected within central area of FNH in 7 patients,and spokewheel color flow was found in 2 patients.These color flow patterns were specific for FNH.Otherwise,the spectral wave of FNH mostly showed a higherly velocity(mean 0.59 m/s) and lower resistive index(mean 0.59 ).Conclusions The color Doppler ultrasound combined with conventional ultraound could raise the accuracy of diagnosing FNH.
