Susceptibility weighted imaging (SWI) uses phase and magnitude data to increase the conspicuity of sources such as blood vessels and hemorrhages. Typical resolution used in clinical SWI are approximately 0.5-1 mm in-plane and 1-2 mm through plane. Higher resolution has been achieved using 7.0 T MRI, but such units have limited availability. In this work, we generated ultra-high resolution (400 µm isotropic) SWI at 3.0 T using registration and averaging.
