Abstract

Background:The detection of renal masses has risen significantly over the past years with the
increasing use of radiological imaging modalities, majority of renal masses are renal cell
carcinoma which account for 80 to 85% of primary renal tumors and approximately 3% of all
malignancies in adults. Dynamic contrast-enhanced MRI assesses the signal dynamics caused
by contrast material transit through the renal cortex, medulla and the collecting
system.Diffusion-weighted imaging (DWI) is a MR modality using strong bipolar gradients to
create a sensitivity of the signal to the thermally induced Brownian (or random walk) motion of
water molecules and in vivo measurement of molecular diffusion. Magnetic resonance provides
a unique opportunity to quantify the diffusional characteristics of a wide range of specimens.
