A novel self-navigated 3D radial whole-heart cine
sequence for combined coronary anatomy visualization and
ventricular function assessment is introduced. The
sequence is not ECG-triggered and allows for the
retrospective selection of both the acquisition window
duration and its relative position in the cardiac cycle.
In addition, multiplanar reformatting at any
user-defined anatomical level is enabled for these 3D
cine datasets. First combined coronary MRA and
ventricular function data obtained with this approach in
vivo and in humans are presented.
