The major question to be answered is whether the mass represents a surgical or nonsurgical lesion or, in some cases, if follow-up studies are necessary. CT urography ( CTU or CT IVU ), also known as CT intravenous pyelography ( CT IVP ), has now largely replaced traditional IVU in imaging the genitourinary tract. Comparative functional studies with scintigraphy have shown high concordance of the two methods [ 5 – 9 ]. IVU has many drawbacks including poor diagnostic accuracy in diagnosis and characterization of parenchymal lesions, also in cases of nonfunctioning kidneys. These structures make up your urinary tract. MRU provides the. Objective: The purpose of our study was threefold: to evaluate the ability of excretory phase CT urography to opacify the urinary collecting system by comparing opacification seen on CT with the opacification seen on a series of unmatched IV urography examinations; to determine the optimal CT urography technique for ureteral filling by comparing studies of.
