Subtraction technique in intravenous aortography.
Excretory urography using the subtraction technique (100 ml of 60% urographic media injected in 10-12 seconds) demonstrated the aorta and its major branches well enough to prove useful clinically. The method is fast and graphic, and risk seems no greater than that associated with the standard urographic examination.
