Body Diffusion Weighted Imaging (DWI) - IVIM


Quibim has developed a noninvasive post-processing application designed to calculate the water molecules diffusivity in tissues, allowing to detect fast water molecules diffusivity from slow water molecules diffusivity. This module calculates IVIM MRI biomarkers (Intra-Voxel Incoherent Motions) by applying the bi-exponential modeling of the diffusion signal with the use of two different b-values. IVIM is an advanced diffusion method that allows the quantification of Diffusion (D), Perfusion (D*) and Vascular Fraction (f) of the tissues.
