Non-sedated, non-contrast rapid pediatric magnetic resonance imaging methods are of great interest to pediatric radiology. In this work, we explore the possibility of a multi-contrast, quantitative method referred to as STAGE imaging for minimizing or eliminating sedation in Sturge-Weber Syndrome by using a k-space sharing strategy which increases the resolution of susceptibility weighted imaging and quantitative susceptibility mapping. Preliminary results show the potential of STAGE which generates more than 10 pieces of qualitative and quantitative information in one 5-minute protocol at 3T.
