Quantitative ultrashort T2 components imaging in the brain using variable flip angle balanced steady state free precession ultrashort echo time MRI
An isotropic sub-millimeter resolution uT<sub>2</sub> fraction map was achieved with a simplified fitting model, and corresponded to expected patterns of myelination. There was a significant uT<sub>2</sub> fraction reduction in MS patients' lesions. The repeatability of the quantification was verified by the consistency between two separate scans.
