Pixyl.Neuro.BV is a volumetry tool measuring brain atrophy. It integrates into the routine workflow to quantify the volume of different tissues and structures in the brain, as well as any changes from the previous visit if there is one (longitudinal analysis). It also compares patient values to a normative population. The software outputs a quantitative report on tissue and structure volume, and changes relative to the prior visit. It also provides graphs to visualize the evolution of certain volumes with respect to normative values.
