Spiral MRI possesses several advantages vs. Cartesian MRI, due to differences in their k-space trajectories and underlying MR physics, which can be leveraged for added value in routine clinical imaging. A Spiral Neuroimaging Cooperative, consisting of nine clinical sites, was formed for the multi-center evaluation of spiral MRI as an alternative to Cartesian MRI in routine clinical imaging. Post-contrast brain spiral 2DT1SE were compared with Cartesian 2DT1SE or TSE. Spirals demonstrated faster scanning with consistent flow artifact reduction vs. both Cartesian options, and superior overall image quality (T1 contrast, lesion visualization) vs. TSE.
