摘  要:目的探讨磁共振NATIVE TrueFISP序列非对比剂肾动脉血管造影的临床应用价值。方法选择39例行肾脏检查的患者,利用德国Siemens 1.5TMR对肾动脉及其分支区域进行NATIVE True FISP序列检查,并进行增强扫描,采用MIP法进行图像重组,获得肾动脉成像。对2组肾动脉图像的质量、肾动脉分支、副肾动脉及静脉伪影显示情况,由2位观察者进行对照分析。结果总体显示两组对图像质量的显示无明显差异;True FISP组对肾动脉分支显示的评分为3.1分,高于CE-MRA组的1.9分(P<0.05);TrueFISP组检出副肾动脉13支,高于CE-MRA组的11支;True FISP组肾静脉伪影的评分为4.7分,高于CE-MRA组的3.9分(P<0.05)。结论使用NATIVE True FISP序列进行非增强型肾动脉成像是可以替代CE-MRA检查的。Objective To investigate the clinical value of NATIVE TrueFISP sequence without the contrast agent in magnetic resonance angiography(MRA) of renal artery. Methods Thirty-nine patients of routine kidney examination were include in this study. M1P images of kidney arteries were reconstructed based on axial images acquired with TrueFISP and contrast enhanced MR angiography(CEMRA) in German Siemens 1.5TMR. The image quality, assessment of renal artery branches, accessory renal artery and renal vein artifact were compared between the two groups. Results were analyzed by 2 observers. Results Overall, no significant difference between the two groups of image quality. Scores for demonstrating renal artery branches in TrueFISP images group were 3.1,which were significantly higher than that of CE-MRA group(1.9). The TrueFISP group detected 13 accessory renal arteries 13, higher than the CE-MRA group which were 11.Scores for renal vein artifact in TrueF1SP images group were 4.7,which were significantly higher than that of CE-MRA group(3.9). Conclusion Non-contrast enhanced magnetic resonance angiography of renal artery with TrueFISP technique can replace the CE-MRA.
