Recent studies investigated the human vasculature by building vascular atlases and performing vessel morphometry. Even though these studies showed great potential, the used resolution might not be sufficiently high to study changes the microvasculature as there occur in i.e. Alzheimer’s. Therefore, an approach to assess the arterial and venous microvasculature in deep gray matter regions is presented. Based on high resolution ToF angiography and QSM acquired at 7T vascular densities and vessel probability maps were computed.
