摘　　要：目的探讨应用多层螺旋CT（MSCT）扫描后处理技术对肝脏局灶性结节增生（FNH）的病理特征显示及诊断价值。方法选择病理和临床证实为FNH的患者24例共27个病灶，经MSCT检查，进行扫描资料和后处理分析。结果24例中22例为单发病灶，2例为多发病灶。平扫16个病灶呈低密度，7个为等密度，4个为高密度（患者为脂肪肝，其中1例为多发）；注射对比剂后，动脉期明显均匀增强17个；实质期表现略高密度13个，等密度10个，稍低密度4个；延迟扫描只有5个呈稍高密度，9个均呈等密度，13个呈低密度。27个病灶中12个病灶检出中央星状瘢痕。有23个可见增粗肿瘤供血动脉，供血动脉完整走行柔和，并见其均匀深入病灶实质组织中。结论综合MSCT扫描后处理中的特征性表现，能够对FNH作出可靠的诊断及鉴别诊断。Objective To investigate and evaluate the pathological features and diagnostic significance of MSCT findings in scan postprocessing for focal nodular hyperplasia （FNH）. Methods A total of 24 patients with FNH who underwent MSCT scan post processing were investigated. The FNH were pathologically and clinically confirmed. Results There are single focus in 22 cases and multiple focus in 2 cases. On plane scan 16 lesions were hypodensity and other 7 isodensity ,4 hyperdensity（ eases with fatty liver）. After contrast, 17 lesions were evenly high enhanced on arterial phase;13 lesions showed still hyperdensity and other 10 lesions isodensity,4 lesions hypodensity on parenehymatous phase. Only 5 lesions were hyperdensity but 9 lesions isodensity and 13 lesions hypodensity on delayed phase. Twelve lesions in 27 were detected with central stella-formed cicatrix. There were thickening tumor feeding arteries in 24 lesions, the artery of which were entered integrated into parenchymatous lesions with soft course. Condusion Synthesizing the charcteristic appearance on MSCT scan postprocessing, doctor could make correct diagnosis and differentiated diagnosis for FNH.
