Whole-heart 3D cine was obtained in 18 sec using kat ARC
technique with acceleration factor of 7.7, following
SSFP 2D cine of the left ventricular (LV) short axis in
21 patients on 3T. LV functional parameters including
EDV, ESV, SV, EF, Mass were compared between 2D and 3D
cine. Bland-Altman analysis revealed the
interchangeability of parameters between 2D and 3D cine,
and inter- and intra-observer variability were excellent
in both techniques. 3D kat ARC cine enables accurate
clinical evaluation of cardiac function within a single
breathhold.
