摘　　要：研究及阐述肝腺瘤的MRI表现与诊断 ,以提高MRI对肝腺瘤的诊断能力。对我院从 1991～ 2 0 0 3年在受检 4 138例肝脏病例中 ,共收集到的 2例材料齐全的肝腺瘤病例 ,并经MRI、CT、US检查及手术和病理证实。 1例肝腺瘤MRI表现为T1WI上高信号 ,T2 WI上稍高信号 ,SPIR(脂肪抑制像 )表现为稍低信号 ,FFE(快速梯度回波 )表现为稍低信号。另 1例肝细胞腺瘤在T1WI为稍低信号 ,T2 WI稍高信号 ,其内见斑片状高信号 ,SPIR表现与T2 WI基本相同。To impove the diagnostic ability of liver adenoma.We studied and investigated MRI features and diagnosis of liver.4138 patients with liver diseases retrospectively analyzed, 2 cases with liver adenoma were found, performed by MRI、CT、US and surgical intervention and confirmed by histopathologic findings. MRI signal characteristic in one patient is hyperintensity on T 1WI, slight hyperintensity on T 2WI, slight hypointensity on SPIR and slight hypointensity on FFE. MRI signal characteristic in another patient is hypointensity on T 1WI, slight hyperintensity on T 2WI and SPIR. The MRI is one of the best diagnostic methods for the preoperative detection of liver adenoma.
