Excerpt
After a long period of stability, imaging of the urinary tract and urothelium has changed dramatically in the past several decades. Excretory urography (EU) was widely used from the 1950s to the 1980s, as EU was able to show the renal collecting systems and ureters non-invasively, unlike retrograde pyelography. EU also provided a cursory evaluation of the renal parenchyma, an evaluation which improved with the addition of nephrotomography. With the introduction of CT, the role of EU began to decline by the early 1980s. CT was quickly identified as being superior to EU for detecting and characterizing renal masses [

3‐
5]. With continuing advances in CT technology, CT is now able to provide an assessment of the urinary tract and urothelium using CT urography (CTU). Multidetector CT technology allows for faster imaging with thin section volume data creating high spatial resolution images. Multidetector CTU can offer a comprehensive CT evaluation of the kidneys and urinary tract. …
