Fresh blood imaging (FBI) is based on subtraction of two
acquisitions done at two different cardiac phases, by
which the background signal cancels out. In clinical
practice, however, we observe residual background signal
after subtraction, which makes it challenging to
visualize the vessels. In this study we sought to add
fat saturation to FBI, in order to suppress better
suppress background signal. We imaged eight patients
with peripheral arterial disease using FBI with and
without fat saturation, and our results show that FBI
with fat saturation improves background suppression
compared with FBI without fat saturation.
