Submillimeter balanced SSFP BOLD–functional MRI accelerated with 3D stack‐of‐spirals at 9.4 T

Purpose This work aims to improve the speed of balanced SSFP (bSSFP) acquisition with segmented 3D stack‐of‐spirals for functional brain studies at ultrahigh field. Methods Functional experiments were performed with an accelerated 3D stack‐of‐spirals sequence with water excitation for fat suppressio...
