摘　　要：目的探讨时间-空间标记反转脉冲(Time-SLIP)技术在不使用对比剂的情况下利用呼吸门控对慢性肾脏病(CKD)患者进行磁共振血管成像的可行性及应用价值。方法使用TOSHIBAEXCELART Vantage 1.5T磁共振,对17例健康者(对照组)及31例慢性肾脏病患者(CKD组)行TimeSLIP肾动脉扫描,由两位经验丰富的MRI医师根据5级评分标准对图像质量进行评价。结果对照组显示36支肾动脉(34支主肾动脉,2支副肾动脉),CKD组显示65支肾动脉(62支主肾动脉,3支副肾动脉)。两名医师均认为,对照组图像质量大于3分者达100%(36/36),CKD组图像质量大于3分者占96.9%(63/65),且两组之间无统计学差异(P>0.05)。分支显示情况,两名医师均认为对照组评分高于慢性肾脏病(CKD)组,且两组之间存在统计学差异(P<0.05)。结论 Time-SLIP技术可用于肾动脉血管成像,是CKD患者肾动脉检查的一个较好的方法。Objective To evaluate the feasibility of non-enhanced renal artery MR angiography （MRA） with respiratory gated time spatial labeling inversion pulse （Time-SLIP） technology in diagnosis of chronic kidney disease （CKD） and its clinical application. Methods 17 healthy volunteers （control group） and 31 CKD patients （CKD group） underwent MRI examination （TOSHIBA EXCELART Vantage 1.5T） with Time-SLIP technology. Two experienced radiologists graded the image quality according to a five-level scale. Results 34 renal arteries and 2 accessory renal arteries were imaged in control group, while 62 renal arteries and 3 accessory renal arteries were imaged in CKD group. Both radiologists pointed out that the number of images whose scores were equal to or above 3 score in control group is 36, accounting for 100%; while the number of images whose scores were equal to or above 3 score in CKD group is 63, accounting for 96.9%. There was no significant difference between the two groups （P〉0.05）. As to the demonstration of branches, both considered that the scores of control group were higher than that of CKD group, and there were significant differences between the two groups （P〈0.05）. Conclusion Time-SLIP technology can be used in renal artery MRA and is a good method to diagnose CKD.
