## Abstract Short image acquisition times and sensitivity to magnetic susceptibility favor the use of gradient echo imaging methods in functional MRI (__f__MRI). However, magnetic susceptibility effects attributed to air‐tissue interfaces also lead to severe signal loss in images of the large infer
