| 摘 要： | 目的探讨肝腺瘤的临床及MRI表现，提高对肝腺瘤的诊断及鉴别诊断能力。方法对经术后病理证实的肝腺瘤患者6例的MR平扫及动态增强扫描资料进行回顾分析，以评价MRI的诊断价值。结果6例患者无明显临床症状，系偶然发现。MR平扫T1WI肿瘤常呈等或稍低信号，部分T1WI反相位图像信号下降，T2WI以高信号为主，瘤内有出血坏死信号不均匀。动脉期呈明显强化或轻～中度强化，部分瘤内出血无强化；门脉期及延迟期扫描强化下降或持续强化。假包膜T1WI为低信号，T2WI为高信号，增强后可呈持续明显强化或延迟强化。结论肝腺瘤临床和MR表现缺乏特异性，了解其常见平扫及动态增强表现，结合临床可提示诊断；对部分表现不典型病例，利用肝脏特异性对比剂可与其它肿瘤鉴别。

| Abstract: | Objective To improve the capability of diagnosis and differential diagnosis of hepatocellular adenoma(HCA) by investigating the clinical and magnetic resonance imaging features.Methods 6 cases of HCA confirmed by pathology were retrospectively analyzed.All cases were performed by precontrast MR scan and dynamic MR scan after intravenous contrast material injection.Results 6 asymptomatic cases were discovered accidentally.On precontrast T1WI tumor's images were iso-or hyperintensity compared with normal live... |
