abstract = {Black blood Fast Spin Echo imaging of the heart is usually
performed during the mid-diastolic rest. This is a direct
consequence of the long inversion time required to suppress the
blood signal, which is constrained by the T1 of the blood, as
well as the heart rate or repetition time. To overcome these
constraints and to acquire black blood images in end-systolic
rest, a new approach is introduced aiming at adaptively
predicting the best time to prepare and acquire MR signals. It
is based on an RR interval prediction algorithm and on a
cardiac cycle model. Applied on fourteen healthy volunteers,
the proposed method is compared to a simple alternative using a
fixed delay and to the standard black blood imaging in mid-
diastolic rest. Results show that the proposed method offers an
increased robustness in terms of trigger delay error and image
quality compared to the tested simple alternative. This is also
demonstrated that the right ventricle is better depicted than
in images acquired with the standard mid-diastolic rest
acquisition, thanks to an image comparison done by an
experienced radiologist, especially the thin right ventricle
free wall.}
