Renal cell carcinomas are a heterogeneous group of
tumors not only with their varying biologic behavior but
also in their response to targeted therapies. Previous
work has shown that IVIM parameters are useful in
differentiating common subtypes of RCC based on whole
ROI analysis. Our results confirm previous work showing
a clear trend separating more vascular (clear cell) from
less vascular (papillary) tumor subtypes using the IVIM
metric fp. Additionally, our initial results suggest
differentiation between benign and malignant subtypes of
renal tumors may also be possible. These findings could
potentially impact surgical planning.
