A quantitative noninvasive MR imaging based disease severity score for late infantile neuronal ceroid lipofuscinosis has been presented. The metric combines data from brain-water apparent diffusion coefficients, the volume percentage of CSF, and N-acetylaspartate-to-creatine metabolite ratios. The methods used used can be adapted to run on multiple scanner platforms in a straightforward manner.
