Transverse relaxivity of Magnevist in the grey and white matter was experimentally estimated with Gd enhanced steady state imaging and dynamic susceptibility contrast imaging experiments using a single dose of the contrast agent. Relaxivity of the contrast agent was found to be significantly different in grey matter and white matter.
