目的：探讨MRI对肝细胞腺瘤(hepatocellular adenoma，HCA)的诊断价值。方法回顾性分析8例经病理证实的HCA的MRI检查资料，均行MRI平扫及动态增强扫描。结果①病灶均单发，圆形或类圆形,边界清晰；肝右叶5例，左叶3例,平均直径5.8cm。4例肿块内有出血；7例有包膜。②MRI平扫：T1WI同相位呈稍低信号5例，等信号2例，稍高信号1例；反相位信号均减低；T2WI稍高信号6例，等或稍低信号2例，DWI稍高信号7例，等信号1例。③MRI增强：6例动脉期明显强化、门静脉期持续强化，延迟期3呈稍高信号,1例呈等信号,2例呈稍低信号。1例动脉期中度强化，1例轻度强化，门静脉期均持续强化，延迟期呈稍低信号。7例有包膜并延迟强化。结论 MRI检查能准确显示HCA的病理成分，可以提高其与肝内含脂质病变的鉴别诊断，在术前做出正确诊断。

Objective To investigate value of MRI in diagnosing hepatocellular adenoma (HCA). Methods MRI findings of 8 cases with HCA proved by pathology were analyzed retrospectively. All were performed MRI plain and dynamic enhanced. Results① All lesions were solitary, and round or oval with clear boundaries;There were 5 cases in right lobe, 3 cases in left lobe, and the average diameter was 5.8cm. There are 4 cases with bleeding, 7 cases with enveloped.②MRI scan:5 cases showed slightly lower signal and 2 cases with equal signal、1 case slightly higher signal on T1WI of in phase, all signals could be seen reduced on out-phase . 6 cases showed slightly higher signal, 2 cases equal or slightly lower signal on T2WI, 7 cases showed higher signal and 1case with equal signal on DWI. ③ MRI enhancement: There were 6 cases significantly enhanced at arterial phase, continued to strengthen at portal venous phase, 3 cases showed slightly signal and 1 case showed equal signal, 2 cases showed slightly lower signal at delayed phase. 1 case moderately enhanced and 1 case mild enhanced at arterial phase, both continued to strengthen at venous phase, with slightly lower signal at delay period. 7 cases with enveloped and delayed enhanced. Conclusion MRI examination could accurately display the pathological component of HCA, improve the differential diagnosis of liver lesions containing lipids and make a correct preoperatively diagnosis.
