Comparison of dynamic and conventional computed tomography, angiography, and ultrasonography in the staging of renal cell carcinoma.
A prospective study was carried out on 22 patients to assess the diagnostic ability to stage renal cell carcinoma by computed tomography, dynamic computed tomography, arteriography, ultrasonography, and radionuclide scanning. Dynamic computed tomography remedied the most consequential diagnostic shortcomings of conventional computed tomography and proved the most sensitive, specific, and accurate technique for staging of all types of contiguous extension of renal cell carcinoma. For the identification of bone metastases, radionuclide scintiscanograms were found most accurate and cost-effective.
