In renal cell carcinoma a differentiation of the histological subtype cannot be stated neither on unenhanced nor on contrast enhanced MR images. MR perfusion studies were performed in a total of 34 patients with renal masses before surgery acquiring a turbo-flash sequence to evaluate whether the perfusion kinetics in contrast-enhanced MRI might allow for further characterization of solid renal masses. The perfusion kinetics of various solid renal masses however did not show significant differences in contrast-enhanced MRI and therefore as well can not be used for further subcategorization of malignant renal tumors.
