Low-dose digital urography in the pregnant patient

In the pregnant patient when visualization of the ureters is requested, excretory urography is often ordered. We propose the use of digital radiography using single exposure as an alternative to conventional urography. This technique allows significant dose reduction while visualizing the entire urinary tract. It can be performed on most current-generation computerized tomographic scanners. In addition to dose reduction, the ability to manipulate, magnify, and avoid repeat exposures makes this an attractive alternative to the conventional film-screen technique.
