We have previously reported acoustically silent functional MRI using a novel pulse sequence known as Looping Star, which has been successfully implemented across distinct paradigms in spite of limitations to image quality and signal-to-noise. Here, we present a recent important improvement of Looping Star and demonstrate its robust performance for both functional imaging (in terms of visual BOLD fMRI) and structural imaging (in terms of T2*-weighted and quantitative susceptibility mapping).
