Cartesian SE or TSE sequence suffers from flow-related
artifacts in post-contrast T1-weighted imaging. A spiral
SE technique has been proposed to reduce the flow
artifacts while providing faster scan speeds. In this
preliminary study, the spiral SE sequence was evaluated
and compared to Cartesian TSE mDixon in the pediatric
group. Both independent radiologists rated spiral SE as
superior to Cartesian TSE on flow artifact reduction and
overall quality. Spiral SE also provides advantages such
as fast scan speed and dark vascular signal. Therefore,
spiral SE provides a viable alternative in post-contrast
T1-weighted imaging.
