Staging of renal adenocarcinoma: role of various imaging procedures.
Since the only successful curative treatment of renal adenocarcinoma is surgery, accurate radiologic information is crucial during initial tumor staging for optimal operative planning. Accurate radiologic staging can be achieved by use of proper imaging techniques, usually a combination of contrast-enhanced CT or multiplanar MR imaging with fast scanning techniques. These techniques permit the demonstration of regional lymph nodes, vascular extension, and distant metastases. Sonography and inferior venacavography are used occasionally to supplement the information obtained from CT or MR imaging. We review the principles of staging of renal adenocarcinoma, emphasizing the strengths and weaknesses of each imaging technique.
