目的：以常规导管血管造影为参照标准，确定屏气、增强对比剂、三维（3D）磁共振（MR）血管造影在评估主动脉髂流入道和肾动脉中的诊断准确性。材料与方法：对39例有症状的周围血管疾病患者进行了导管和增强后的3D MR血管造影。在一项前瞻性盲法分析中，评估每个血管段（每动脉树23段）是否存在梗阻性狭窄，通过MR血管造影分级为轻度（50%）或闭塞，敏感性和特异性分别为肾动脉93%和98%，髂总动脉96%和100%，髂外动脉93%和93%，髂内动脉96%和94%。结论：对比增强3D MR血管造影的诊断性能与导管血管造影相当，可用于周围血管疾病患者治疗前的主动脉、肾动脉和盆腔动脉系统评估。
PURPOSE: To determine the diagnostic accuracy of breath-hold, contrast material-enhanced, three-dimensional (3D) magnetic resonance (MR) angiography in the assessment of the aortoiliac inflow tract and renal arteries with conventional catheter angiography as the standard of reference.MATERIALS AND METHODS: In 39 patients with symptomatic peripheral vascular disease, both catheter and contrast-enhanced, 3D MR angiography were performed. In a prospective blinded analysis, each vascular segment (23 segments per arterial tree) was evaluated for the presence of obstructive stenosis, graded as mild (50%) or occlusions with MR angiography, sensitivity and specificity, respectively, were 93% and 98% for the renal arteries, 96% and 100% for the common iliac arteries, 93% and 93% for the external iliac arteries, and 96% and 94% for the internal iliac arteries.CONCLUSION: The diagnostic performance of contrast-enhanced 3D MR angiography is comparable with that of catheter angiography and thus may contribute to assessment of the aorta, the renal arteries, and the pelvic arterial system in patients with peripheral vascular disease before they undergo therapy.
