MR CINE acquisitions represent the gold standard for the
assessment of left ventricular function. Although
recently introduced single breath-hold real-time 2-D
CINE and 3-D CINE acquisitions feature a high in-plane
resolution, small details could be missed by the low
spatial resolution in slice direction. To address this
limitation, a single breath-hold 3-D CINE acquisition is
proposed in this work featuring an isotropic resolution
below 2 mm. In-vivo experiments were performed on 5
healthy volunteers and cardiac function was compared to
gold standard 2-D CINE.
