Body
was changed:
CT-intravenous urography has now largely replaced traditional IVU in in imaging the genitourinary tract. It gives both anatomical and functional information, albeit with a trade off against a higher dose of radiation.
The aim is to illustrate the collecting systems, ureters and bladder with intravenous contrast, albeit in a single acquisition as opposed to the multiple and more dynamic traditional IVU.
Upper tract tumours, strictures and to a degree the function of the kidney can be assessed.
A variation of techniques have been described.1.
A CT-IVU may be performed along or in conjunction with other CT studies of the genitourinary tract, such as a 3 or 4 phase or split bolus study.
