In this perspective study the authors examined 57 patients to evaluate diagnostic accuracy of sequential angiourography (AUS) using spot-camera and image subtraction for the visualization of the vascular phase of the renal arteries. All the subjects underwent surgery or follow-up with other clinical and radiological methods. The results obtained with this technique, of low cost and simple execution, were satisfactory: accuracy 98%, sensitivity 100%, specificity 98%.
在这项前瞻性研究中，作者检查了57例患者，以评估使用点相机和图像减法的序贯血管造影术（AUS）对肾动脉血管期可视化的诊断准确性。所有受试者均接受了手术或采用其他临床和放射学方法进行随访。这项技术成本低且操作简单，所获得的结果令人满意：准确率98%，灵敏度100%，特异性98%。
