Answer

Contrast-enhanced CT scanning has become the imaging procedure of choice for diagnosis and staging of renal cell cancer and has virtually replaced excretory urography and renal ultrasonography. Ultrasonographic examination can be useful in evaluating questionable cystic renal lesions if CT imaging is inconclusive. Large papillary renal tumors are frequently undetectable by renal ultrasonography.
