摘　　要：目的评价多层螺旋CT三期增强扫描对肝腺瘤的诊断价值，探讨肝腺瘤的cT三期增强扫描表现特征。方法收集10例经手术病理证实的肝腺瘤患者的多层螺旋CT图像，结合文献对其临床、病理和影像学表现进行回顾性分析。结果10例肝腺瘤均为单发肿块，直径为4．0～13．2cm，10例平扫均呈边界清楚、略低密度灶，除3例因出血、坏死外密度均较均匀；动态增强扫描，病灶动脉期明显强化，门脉期和延迟期呈等或略低密度灶。结论肝腺瘤的CT表现具有一定的特征，多层螺旋CT动态增强检查再结合其临床特点对其诊断与鉴别诊断具有重要价值。Objective To evaluate diagnostic value of three-phase enhanced MSCT in hepatocellular adenoma as well as its CT appearance. Methods Ten cases of hepatocellular adenoma conformed by surgery and pathology were retrospectively analyzed. Results Ten cases were single mass,the diameter of lesions ranged from 4.0-13.2 cm. In plain CT, the lesions were slight hypodensity with margins clear except three caces with hemorrhage or necrosis.In the ten cases,the typical MSCT findings of hepatocellular adenoma included obvious enhancement in the arterial phase, and in the portal venous and delay phase the lesions shown isodensity or slight hypodensity by dynamic contrast scanning. Conclusion Hepatocellular adenoma CT signs have certain characteristics,application of multi-phase dynamic contrast exam close linlts clinical data has important valua in diagnosing hepatocellular 4denoma.
