Self-navigation may be used to perform respiratory
motion correction in whole heart coronary MRA, improving
scan efficiency and ease of use when compared to
navigator-gated approaches. However, signal from the
chest wall complicates motion detection. Additionally,
streaking artefacts secondary to displacement correction
may be introduced. By incorporating a "pencil beam" 2D
RF pulse into a T
2
-Prep module, one may
create a "2D- T
2
-Prep" that combines T
2
-weighting
with the intrinsic spatial selectivity of a 2D pulse.
Here, we combined a 2D- T
2
-Prep with
self-navigation and present initial
in
vivo
results demonstrating that image quality is
improved through the use of a 2D- T
2
-Prep.
