摘要
目的:评估MRI诊断肝腺瘤的的价值。材料和方法:回顾性分析经病理证实8例肝腺瘤的MRI表现和术前或活检前诊断,并与病理所见对照。结果:6例诊断为良性肿瘤并考虑到肝腺瘤的可能性,2例误诊为肝癌。8例共11个病灶,T1WI 8个呈高信号、3个呈低信号;T2WI 10个呈高信号,1个呈低信号;6个病灶有假包膜,3个病灶含脂质或脂肪。注射Gd-DTPA行增强扫描,所有病灶动脉期中度至明显不均匀增强、门静脉期和延迟期轻度增强。结论:大多数肝腺瘤在术前或活检前MRI正确诊断是可能的。
Purpose： To evaluate the diagnostic value of MR imaging for hepatic adenomas. Materials and Methods： The MR imaging features of 8 patients with hepatic adenomas proved pathologically were retrospectively analyzed and correlated with pathologic findings after operation or biopsy. Results ： Six cases were diagnosed as benign tumors （ the possibility of hepatic adenoma was considered） and 2 cases were mistaken for malignant tumors. Eight patients had 11 hepatic masses, 8 lesions were hyperintense and 3 hypointense on T1WI, and 10 lesions were hyperintense and 1 lesion hypointense on T2WI. Six lesions showed pseudocapsule and 3 lesions contained lipid or fat. All lesions showed moderate or strong enhancement during arterial phase and slight enhancement during portal venous phase and delayed phase. Conclusion ： It is possible that most of hepatic adenomas can be correctly diagnosed by MR imaging preoperatively or before biopsy.
