摘要 目的探讨MRI化学位移同反相位成像技术在少脂肪肾错构瘤诊断的应用价值。方法回顾性分析经手术病理证实的17例CT平扫肿块内均未见成熟脂肪密度影的少脂肪肾错构瘤MRI同反相位表现,同时结合其他MRI表现。结果目测法17例中,9例病灶在反相位信号较同相位弥漫性或局限性降低,3例在反相位信号无明显下降,但在脂肪抑制T2WI上病灶内高信号成分被抑制。5例病灶在反相位和脂肪抑制T2WI都无明显信号改变。其他MRI表现:14例T2WI呈均匀低信号,3例呈混杂信号。17例均未见假包膜。增强扫描17例均强化较均匀,10例皮质期中度强化,4例明显强化,实质期及肾盂期持续强化,3例呈一过性强化,即"快进快出"强化方式。结论 MRI化学位移同反相位成像技术,结合MRI其他表现,有助于对少脂肪肾错构瘤的鉴别诊断。
