1. A computer-implemented method for determining a fetus ventricular volume from magnetic resonance diffusion-weighted imaging (DWI) images, comprising:
A) acquiring DWI images, having a pre-set voxel height, of a fetus ventricle, wherein acquisition is made with a single b-value selected in a range between 200 and 1000 s/mm2;
B) selecting a region of interest (ROI) on each of the DWI images around the fetus ventricle;
C) automatically clusterizing pixels in the ROI, obtaining clusterized DWI images; and
D) calculating the fetus ventricular volume based on the number of pixels in the ROI for each of the DWI images and the pre-set voxel height.
