Fifty-nine patients with occlusive disease of the aorto-iliac and femoro-popliteal arteries were investigated prospectively by intravenous (IV) or intraarterial (IA) digital subtraction angiography (DSA) and magnetic resonance angiography (MRA). This was accomplished using a two-dimensional (2D) Inflow- (59 patients) and a 2D Phase Contrast- (RSE--rapid sequential excitation) sequence (29 patients). The spectrum of pathology included stenoses < 50%, stenoses 50-89%, stenoses 90-99%, occlusions, aneurysms and status following reconstructive surgery. MRA- and DSA-examinations were evaluated by four radiologists. The diagnoses were made by consent decisions of a radiologist and a vascular surgeon based on clinical and radiological findings. Diagnostic performance of IA-DSA was superior to all other imaging modalities. Vascular delineation of 2D Inflow-MRA was comparable to that of IV-DSA. The image quality of RSE-MRA was not adequate for diagnosis. In conclusion, 2D Inflow-MRA is a promising method for evaluating abdominal and peripheral arteriosclerotic disease. Interpretation of MR-angiograms, however, requires profound knowledge of MRA-techniques, X-ray angiography and hemodynamics.
对59例主-髂动脉和股-腘动脉闭塞性疾病患者进行了前瞻性研究，采用静脉内（IV）或动脉内（IA）数字减影血管造影（DSA）及磁共振血管造影（MRA）。这是通过二维（2D）流入成像序列（59例患者）和二维相位对比成像序列（RSE——快速序列激发，29例患者）来完成的。病理类型包括狭窄＜50%、狭窄50% - 89%、狭窄90% - 99%、闭塞、动脉瘤以及重建手术后的情况。由四位放射科医生对MRA和DSA检查进行评估。诊断由一位放射科医生和一位血管外科医生根据临床和放射学检查结果共同决定。IA-DSA的诊断性能优于所有其他成像方式。2D流入成像MRA的血管显示与IV-DSA相当。RSE-MRA的图像质量不足以用于诊断。总之，2D流入成像MRA是评估腹部和周围动脉硬化性疾病的一种有前景的方法。然而，对磁共振血管造影的解读需要对MRA技术、X线血管造影和血流动力学有深入的了解。
