## Abstract

PROJECT SUMMARY
Renal cancer is a source of severe mortality and morbidity, not only due to the primary malignancy but also due
to loss of renal function (sometimes leading to chronic kidney disease) after partial nephrectomy. Methods to
noninvasively monitor renal function and predict its robustness against this decline of function are therefore in
high demand. Diffusion-weighted MRI is well poised to play this role as an adjunct to renal cancer patients'
existing clinical MR workup. Our group has been at the forefront of research into advanced renal diffusion MRI
contrast, including methods to separate microstructure from microcirculation (intravoxel incoherent motion
(IVIM)) and assess microscopic anisotropy (diffusion tensor imaging (DTI)). A recent comprehensive approach
(REFMAP) collects these contrasts jointly, allowing assessment of microstructural and microcirculation
anisotropy. We propose to apply this composite dataset both to classify aggressiveness of the primary renal
lesion and to assess and predict post-surgical renal function.
IVIM-MRI will be performed to characterize the aggressiveness of the primary lesion. The REFMAP-MRI protocol
will be used to evaluate renal cancer patients before surgery and at 1 year follow up, in comparison with standard
clinical workup (measured glomerular filtration rate, proteinuria). Cross-sectional correlation will validate the
markers of the REFMAP-MRI technique as probes of renal function, and those baseline values predicting which
patients experience renal function decline will be identified.
