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.
