Spiral computed tomography (CT) is the state of the art today in imaging many features of the genitourinary tract. The use of dual-phase CT imaging improves our ability to detect and stage a wide range of pathologies. However, imaging in the arterial phase has several potential pitfalls that can result in either overcalling or undercalling genitourinary pathology. This paper reviews some of the common pitfalls and presents strategies on how to avoid them.
