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.
