Noncontrast multidetector CT of the kidneys: utility of 2D MPR and 3D rendering to elucidate genitourinary pathology.

To encourage routine use of 2D multiplanar reconstructions (MRPs) and 3D renderings when interpreting noncontrast computed tomography (CT) of the kidney, as this practice can unveil findings related to the kidney or its vasculature that are not apparent on axial sections. Inspecting the kidneys or characterizing CT findings with both axial sections and MPRs may facilitate identification of vascular and neoplastic pathology.
