Three‐dimensional simultaneous brain mapping of T1, T2, and magnetic susceptibility with MR Multitasking

PURPOSE: To develop a new technique that enables simultaneous quantification of whole-brain T₁ , T₂ , $T_2^{\ast }$ , as well as susceptibility and synthesis of six contrast-weighted images in a single 9.1-minute scan. METHODS: The technique uses hybrid T₂ -prepared inversion-recovery pulse modules and multi-echo gradient-echo readouts to collect k-space data with various T1, T2, and $T_2^{\ast }$ weightings. The underlying image is represented as a six-dimensional …
