摘要 【目的】研究小肝癌动态增强 MRI 扫描特点和动态增强在小肝癌诊断中的作用。【方法】对25例怀疑肝脏占位的病人行常规 MRI 检查(包括 T1W/WATS、T2W/TSE、T2W/SPIR)和动态增强扫描。分析 HCC 动态增强的 MRI 特点和病灶分化程度。【结果】T1W/WATS、T2W/TSE、T2W/SPIR、动态增强扫描分别检出病灶26、29、29、33个,动态增强扫描90%(30/33)病灶在动脉期强化。在动脉期高于或等于肝脏实质,门静脉期低于肝实质的强化类型中,低分化 HCC 的比例显著高于其他强化类型。动脉期和门静脉期均高于或等于肝脏实质强化类型中,高分化 HCC 的比率明显高于其他类型。【结论】表明动态增强 MRI 对小肝癌病灶的检测和定性方面具有一定的作用,并在一定程度上反映病灶的分化程度。
