We demonstrate a continuous 3D balanced SSFP cardiac
cine imaging in humans at 3Tesla. The technique is based
on a golden-ratio Cartesian radial sampling with
isotropic spatial resolution. The SAR reduction is
achieved with a variable flip angle scheduling in which
the flip angle is linearly weighted based on the
distance from the k-space origin within the 2D phase
encoding plane. Results demonstrate adequate depiction
of the blood and myocardium borders, which allows for
quantification of the ventricular function.
