In recent years a conceptually different approach for collecting MR data has emerged, based on progressive Spatiotemporal-Encoding (SPEN) of the magnetic spins. This approach extends the capabilities MRI, allowing users to overcome sizable macro- and microscopic field inhomogeneities by altogether freeing the spins evolution from T2* effects, while owing to its lack of aliasing enables the use of limited FOVs. This work demonstrates the potential of SPEN for imaging at ultra high spatial resolutions a regime that is hard to realize using standard k-space encoded Gradient-Echo or SpinEcho protocols owing to T2* related broadening of their acquisition point-spread-functions.
