Multiple MR-techniques for functional tumor evaluation are available, however correlation of these techniques has not been investigated. A protocol comprising Diffusion weighted Imaging (DWI), Blood oxygen level dependent (BOLD) and Dynamic contrast enhanced (DCE)-MRI is feasible for assessment of primary RCC. BOLD moderately correlates to perfusion derived from DCE-MRI. ADC shows moderate correlation to the extracellular volume, but does not correlate to tumor oxygenation or perfusion as it provides mixed information on both perfusion and cellularity. IVIM analysis may resolve this ambiguity. Tumor permeability does not correlate to any other functional parameter.
