abstract = {A modified interleaved flyback (miFB) approach is
introduced, designed to mitigate flow artifacts caused by
alternating readout polarities in Echo Planar Imaging (EPI),
while preserving acquisition efficiency.We propose
reconstructing odd and even echoes of 3D-EPI separately. To
this end, the respective missing lines are acquired in
interleaved shots with inverted polarity and an additional
gradient pre-lobe. Thereby, high scan efficiency is
maintained compared to unsampled flyback gradients. Our miFB
approach is additionally combined with gradient moment
smoothing and compared to the interleaved dual-echo with
acceleration (IDEA) method in phantom and in vivo scans at 7
Tesla.Our results demonstrate a significant reduction in
ghosting and signal dropout using the miFB approach,
yielding comparable image quality to non-EPI acquisitions
while reducing acquisition time by approximately half.The
miFB approach offers a substantial reduction in flow
artifacts, allowing for decreased acquisition times in
TOF-MRA.},
