Magnetic resonance imaging in the staging of renal cell carcinoma.
Correct diagnosis and accurate staging of renal cell carcinoma are critical in the evaluation of prognosis and subsequent treatment planning. Between October 1989 and April 1993, 25 patients with histologically proven renal cell carcinoma (RCC) were studied, comparing magnetic resonance imaging (MRI), computerized tomography (CT), operative findings and histopathological results. Two patients with pT3 tumours were understaged by both methods as T2. Three other patients staged as T4 by CT and T3 by MRI were actually pT3. N and V status were accurately detected by both imaging modalities. One patient with biopsy-proven liver metastasis missed by CT was correctly diagnosed by MRI. We conclude that MRI is complementary to CT and is especially helpful in patients with advanced stage and large sized tumours.
