| 摘 要： | 目的评价4种GRE序列在原发性肝癌锰福地吡三钠(MnDPDP)增强MRI检查中的价值。方法对13例原发性肝癌患者进行常规平扫和MnDPDP增强扫描。平扫序列为T1W FLASH、压脂FLASH、同相位与反相位FLASH,以及T2W TSE,静脉滴注MnDPDP后30 min开始增强扫描,并进行24 h延迟成像,采用与平扫相同的T1W序列。计算肝脏及病灶信噪比(SNR)及病灶与肝脏的对比噪声比(CNR)。结果4种GRE序列成像SNR和CNR无显著性差异(P>0.05),但反相位能检出常规FLASH和同相位无法显示的肝癌脂肪变性。结论同反相位序列可反映肝癌脂肪变性特征,检查简便,在对肝癌患者进行MnDPDP增强MRI检查时建议常规采用。
