Myocardial BOLD CMR is an appealing alternative to
contrast-enhanced methods for the functional assessment
of coronary artery disease. While significant advances
have been made in BOLD CMR, limitations still exist. An
ideal BOLD CMR method would be able to overcome the
limitations by permitting acquisition of 3D myocardial
BOLD images as maps (T2 or T2*) within 5 minutes,
without the need to suspend breathing. In this work, we
developed a stack-of-stars k-space acquisition scheme,
which permits 100% acquisition efficiency, to construct
3D T2 maps with full LV coverage within 5 minutes. We
tested this approach in healthy human volunteers.
