CT urography and MR urography are evolving modalities that surpass intravenous urography, which was the prior mainstay of urinary tract imaging. [23] CT urography provides a detailed anatomic depiction of the urinary tract. MR urography has the advantage of not using ionizing radiation and has the potential to provide more functional information than CT. However, MR urography is less established than CT urography and is less reliable in providing diagnostic image quality. [23]

CT urography and MR urography are currently used in the evaluation of hematuria and will become more applicable to the study of other urologic problems.
