Acquisition of Multi-echo (ME) EPI has recently been shown to be a robust and reliable method for extracting valuable information from fMRI data. In this work, we combine a blipped CAIPI Simultaneous Multiple Slice (SMS) of Multi-echo EPI acquisition with a robust pipeline for reconstruction of time resolved phase and QSM data. Magnitude, Phase and QSM contrasts, which were acquired in one single shot, are shown for multiple echo times. In the future, this type of data can help to determine physiological underpinnings of BOLD activation.
