The rapid intravenous injection of a large bolus of contrast medium produces a vascular as well as a tubular nephrogram. They are additive but the vascular phase is early, intense, and brief whereas the tubular phase is less intense but more prolonged. The addition of tomography during either phase improves visualization of the renal parenchyma and its outline. A comparison study of tomography during the vascular phase (vascular nephrotomography) with that at five minutes demonstrated the superiority of the former. Our technique, data, and illustrative case abstracts are presented.
快速静脉注射一大团造影剂会产生血管造影和肾小管造影。两者是叠加的，但血管期出现早、强度高且持续时间短，而肾小管期强度较低但持续时间更长。在任何一个阶段进行体层摄影都能改善肾实质及其轮廓的可视化。对血管期体层摄影（血管肾体层摄影）与五分钟时的体层摄影进行的比较研究表明前者更具优势。本文介绍了我们的技术、数据及典型病例摘要。
