| 摘 要： | 目的:探讨肝脏局灶性结节增生(FNH)的MRI表现及其病理基础.方法:回顾性分析26例手术病理证实的FNH患者MRI平扫(T1WI、T2WI及DWI)和动态增强扫描的资料,对病灶信号及强化特点进行评价.结果:26例共33个病灶,单发型23例,多发型3例.实质部分于T1 WI显示31例,其中低信号3例、略低信号28例；T2WI显示32例,其中略高信号25例,高信号7例；DWI显示29例,其中略高信号21例,高信号8例.共21例病灶显示中央瘢痕,其中T1WI显示19例,均为低信号；T2WI均可显示,且均呈高信号；DWI显示15例,均为高信号.增强后,实质部分均于动脉期明显、均匀强化,延迟扫描呈略高信号28例,等信号4例,略低信号l例.中央瘢痕于动脉期明显强化1例,延迟期仍持续强化,余32例均表现为延迟强化.8例病灶周围可见增粗、扭曲的供血动脉,4例病灶周围见不完整的环形包膜样延迟强化影.结论:MRI能全面展示FNH病理改变及血流动力学特征,DWI可以提供辅助诊断信息.

| Abstract: | Purpose:To investigate the imaging findings of hepatice focal nodular hyperplasia(FNH).Methods:The MRI data of 26 patients with pathologically confirmed FHN were retrospectively analyzed.The signal intensity of FNH at T1WI,T2WI as well as diffusion-weighted imaging and enhancement pattern was evaluated.Results:Total 33 lesions were detected in 26 patients.Twenty-three had 1 lesion each,and the remaining 3 had multiple lesions.Solid components of FNH showed hypointensity(3/31) or slightly hyperintensity(28/3... |
