Respiration induced dynamic field map changes in the brain are quantified and the influence on the magnitude signal (physiological noise) is investigated. Dynamic off‐resonance correction allows to reduce the signal fluctuations overlaying the blood oxygenation level dependent signal in T2* ‐weighted functional imaging.
