A 14-inch image intensifier designed for digital radiography has made feasible adjunctive evaluation of the renal parenchyma and collecting structures following intravenous digital subtraction angiography (DSA). Initial experiments with rabbits showed digital nephrography to be superior to film-based nephrotomography in terms of renal conspicuity and imaging flexibility. Preliminary experience with 30 patients undergoing DSA reaffirms the suitability of this method for the evaluation of renal anatomy and function. Only about half the amount of contrast material needed for conventional excretory urography is required.
一种专为数字放射摄影设计的14英寸影像增强器，使得在静脉数字减影血管造影（DSA）后对肾实质和集合结构进行辅助评估成为可能。对兔子的初步实验表明，数字肾造影在肾脏显影和成像灵活性方面优于基于胶片的肾断层摄影。对30例接受DSA的患者的初步经验再次证实了该方法在评估肾脏解剖结构和功能方面的适用性。所需的造影剂仅为传统排泄性尿路造影所需量的一半左右。
