摘　　要：目的评估超声造影(CEUS)在肝内增生性病灶-肝局灶性结节性增生(FNH)和肝结节再生性增生(Nodular regenerative hyperplasia,NRH)中的诊断价值。方法所有12例病例包括10例FNH,2例NRH,均行CEUS,并应用时间-强度曲线,得到病灶内和肝实质的增强模式曲线图。结果10例FNH有11个病灶,CEUS表现:动脉相11个(11/11)病灶表现为高增强,其中3个(3/11)病灶表现为典型的离心型轮辐状强化;门脉相11个(11/11)病灶表现为等增强;延迟相有6个(6/11)病灶表现为等增强,5个(5/11)病灶表现为高增强。2例NRH有2个病灶,动脉相表现为高增强,其中1例为离心型轮辐状强化;在门脉相、延迟相均为等增强。结论CEUS可明显提高肝内增生性病变的诊断准确性。Objective To evaluate the usefulness of contrast-enhanced ultrasound （CEUS） in the diagnosis of liver proliferative lesions- focal nodular hyperplasia （FNH） and nodular regenerative hyperplasia （NRH）. Methods CEUS was performed on 10 FNH and 2 NRH in all 12 patients. Enhanced curve patterns were obtained using ACQ time-intensity curve analysis software. Results Eleven FNH （11/11,100%） showed hyperechoic in the arterial phase and isoechoic in the portal phase. During the late phase 6 （6/11） nodules appeared isoechoic and 5 （5/ 11） nodules appeared hypereehoie compared with the adjacent hepatic parenehyma. Only 3 （3/11） nodules had centrifugal wheel-shaped enhancement pattern during the early arterial phase. Two cases with NRH exhibited homogeneous hyperechoie in the arterial phase, isoeehoie in the portal phase and late phase. Conclusions Compared to the pathological diagnosis of FNH, the coincidence rate of CEUS was 81.8% （9/11 ）. CEUS may obviously improve the diagnostic accuracy of liver proliferative lesions.
