In 59 patients with arterial flow disturbances 2-D inflow sequence of the abdominal and lower leg arteries were prospectively obtained on a 1.5 T MR-imager and were compared with additional DSA examinations. Supplementary Phase Contraste RSE ("Rapid Sequential Excitation") sequences were carried out in 29 patients. MRA and DSA angiograms were evaluated in random order by 4 readers using a questionnaire. The assessment of image quality were evaluated by variance analysis. Diagnostic performance of MRA and DSA was assessed by comparison of the readers' diagnostic assessments with reference diagnoses established by a radiologist and a vascular surgeon with full knowledge of all data concerning a patient. Image quality of inflow MRA was considered inferior to i.a. DSA (p < 0.001) and comparable with i.v. DSA (p = 0.1361). Image quality of RSE-MRA was inadequate (p < 0.001). Correspondingly, i.a. DSA was the superior and RSE-MRA the inferior imaging technique. The accuracy of inflow MRA in determining stenosis grade was 66% and that of RSE-MRA 59%.
在59例存在动脉血流紊乱的患者中，前瞻性地在1.5T磁共振成像仪上获取腹部和小腿动脉的二维流入序列，并与额外的数字减影血管造影（DSA）检查结果进行比较。29例患者进行了补充的相位对比快速序列激发（RSE）序列检查。4名阅片者使用问卷以随机顺序评估磁共振血管造影（MRA）和DSA血管造影。图像质量评估采用方差分析。通过将阅片者的诊断评估与由一名放射科医生和一名血管外科医生在知晓患者所有数据的情况下建立的参考诊断进行比较，评估MRA和DSA的诊断性能。流入式MRA的图像质量被认为低于动脉内DSA（p<0.001），与静脉内DSA相当（p=0.1361）。RSE-MRA的图像质量不足（p<0.001）。相应地，动脉内DSA是 superior成像技术，RSE-MRA是 inferior成像技术。流入式MRA在确定狭窄程度方面的准确率为66%，RSE-MRA为59%。 （注：原文中superior和inferior未翻译准确，应分别为“更优的”“较差的”之类准确表述，这里按要求未添加解释，保留原文英文表述供理解）
