In body & breast imaging, pulsatility artifacts are
often observed due to high aortic flow or cardiac
motion. We proposed a slice-selective Motion-sensitized
driven-equilibrium (MSDE) technique that enables
selective suppression of unwanted flow signal in user
specific planes, ideally outside of the main region of
interest (ROI). In this study, we have shown the
feasibility that slice selective MSDE can be applied
outside the main ROI to suppress upstream flow, and the
SNR at the main ROI would not be affected while
achieving blood suppression effect.
