目的 探析螺旋CT平扫及三期 增强扫描应用于肝脏局灶性结节增生 (Hepatic Focal Nodular Hyperplasia, FNH)诊断的临床应用价值。方法 以我院 2012年1月-2015年11月期间收治30例肝脏 局灶性结节增生患者作为研究对象，均行 螺旋CT平扫及三期增强扫描，观察FNH的 CT影像学表现，总结征象特点。结果 肝 脏局灶性结节增生的CT平扫呈略低或等密 度、中央疤痕低密度；动脉期除疤痕外均 呈现明显均匀强化、门脉期呈等或略高密 度、延迟后呈等或略低密度；病灶中央或 周边可见明显增粗、扭曲的供血动脉。结 论 肝脏局灶性结节增生的螺旋CT平扫及 三期增强扫描影像表现具有明显特点，利 于诊断，同时也可与肝细胞癌、血管瘤、 腺瘤等肝脏其它病变进行鉴别，应用价值 高。

Objective To investigate the clinical application value of spiral CT plain scan and three-phase enhanced scan in the diagnosis of hepatic focal nodular hyperplasia. Methods 30 cases of patients with hepatic focal nodular hyperplasia treated in our hospital from January 2012 to November 2015 were treated as the research objects. All underwent spiral CT plain scan and three-phase enhanced scan. CT imaging findings of FNH were observed and the characteristics of the signs were summarized. Results CT scan of hepatic focal nodular hyperplasia showed slightly lower or equal density, low density of central scar; In the arterial phase, except for scar, all showed significant homogeneous enhancement and in the portal phase, it showed equal or slightly higher, after being delayed, showed equal or slightly lower density. There were significantly enlarged and distorted blood supply arteries in central or peripheral lesions. Conclusion CT plain scan and three-phase enhanced scan of hepatic focal nodular hyperplasia are of obvious imaging features, which is beneficial to diagnosis and can be used for the diagnosis of hepatocellular carcinoma, hemangioma, adenoma and other hepatic lesions. The application value is high.
