摘　　要：目的:探讨肘正中静脉和足背静脉穿刺点对肾动脉磁共振成像的影响。方法:选取本院2013年6月-2014年11月需行肾动脉磁共振成像患者32例,随机分为两组,分别选用肘正中静脉处和足背静脉处作为穿刺点,行肾动脉磁共振成像,采用Test Bolus监测两组肾动脉成像峰值时间,选用Cor Cemra FT序列行肾动脉成像,评价两组图像的血管信号强度,信噪比(SNR)和图像对比信噪比(CNR)及重建血管评分。结果:32例均完成检查,两组延迟峰值时间分别为:肘正中静脉点为(24±3.4)s,足背静脉点为(45±5.1)s,两组比较差异有统计学意义(P<0.05);另外共有67支肾动脉显影,12例肾动脉未见异常,狭窄21支,另有1支完全闭塞。两组肾动脉开口处的信号强度分别为(751.25±14.2)、(738.98±31.3);SNR分别为(73.11±4.5)、(71.96±9.5);CNR分别为(41.74±9.3)、(40.24±12.6),比较差异均无统计学意义(P>0.05)。重建肾动脉像均达到诊断要求。结论:肾动脉磁共振成像中,当肘正中静脉等上肢静脉穿刺失败时,足背静脉可为备选,能够满足临床需求。Objective： To investigate the influence of median cubital vein and dorsal venous puncture point on renal artery magnetic resonance imaging.Method：32 patients on renal artery magnetic resonance imaging treated from June 2013 to November 2014 in our hospital were selected and randomly divided into two groups,respectively chosen median cubital vein and dorsal vein as the puncture point to proceed renal artery magnetic resonance imaging,the Test Bolus was used to monitor two groups of renal artery imaging peak time,Cor Cemra FT sequence was chosen for renal artery imaging to evaluate the vascular signal strength of the two sets of image,signal to noise ratio（SNR） and image contrast to noise ratio（CNR）and reconstruction of vascular score.Result：All of the 32 cases completed the inspection,two groups of peak time delay,respectively：median cubital vein point was（24±3.4）s,the dorsal vein of foot point was（45±5.1）s,the differences were significant（P〈0.05）.There were totally 67 renal arteries imaging,12 cases of renal artery were normal,21 cases were stenosis,and 1 artery was totally occlusion.Two groups of signal intensity at the renal arteries openings were（751.25±14.2）,（738.98±31.3）;SNR were（73.11±4.5）,（71.96±9.5）;CNR were（41.74±9.3）,（40.24±12.6）,there was no statistical difference（P〈0.05）.Reconstruction of renal artery both reached the requirement of diagnosis,with no difference between the two groups.Conclusion：When the median cubital vein upper limb venous puncture failure,dorsal vein can be optional to meet the clinical demand at renal artery magnetic resonance imaging.
