Intravoxel incoherent motion (IVIM) DWI has recently
shown potential to assess functional changes of renal
fibrosis. From the findings through multi-b DW-MRI
measurements on cisplatin induced rodent renal fibrosis
models, the temporal variation of ADC values behaved as
a weight of the true diffusion and pseudo-diffusion. The
biomarkers resulted from mono-exponential model
exhibited a dual phase temporal variation, while those
from bi-exponential model remained a single tendency of
variation. According to the histopathological
observation that the worsening of renal fibrosis with
time, the bi-exponential model might be a better choice
for an accurate indication of the evolution of renal
fibrosis.
