About the work
For telencephalic structures, one can compute the yearly rate of relative atrophy, comparing the change in the volume of ROIs, with the change of volume in the lateral ventricle system
yrR*A= (A1-A2) x 1200 / (B1-B2) x (#months between MRI studies) where * is the ROI A1 is the volume of the ROI in the first MRI and A2 the volume of the ROI in the second MRI B1 is the volume of the ventricular system in the first MRI and B2 the volume of the ventricular system in the second MRI
