abstract = {Cardiac MRI is still challenging due to the perpetual heart
motion. In order to avoid cardiac motion artifacts,
acquisitions are synchronized with heart
activity, generally by triggering on R-waves of the
Electrocardiogram (ECG). Double Inversion Recovery Fast Spin
Echo (DIR-FSE) sequences, resulting
in black-blood images, require furthermore specific timing. For
such acquisitions, inversion time (TI) is needed to cancel
blood signals (~500ms) [1],
making acquisitions in the first 500ms of the cardiac cycle
impossible. Black-blood imaging allows then only diastolic view
of the heart. Moreover heart
rate (HR) variability has been shown to be important during
breath-holds [2] making cardiac synchronization even more
complicated.
In this paper, a RR interval prediction method has been
implemented, which permits to launch DIR pulses before R waves
and thus enables black blood
systolic imaging.}
