Characteristics of different cine acquisition strategies.

Method	(× overlaps)	Spatial resolution (mm)	Temporal resolution (ms)	Myocardium SNR (mean ± SD)	Blood-to-myocardium CNR ()	Total scan time (s)	% time saving
CONV	16 2D slices	1	27			270	—
2-SA			40			48	82%
1-SA			40			20	93%
2-AXIAL			40			48	82%
1-AXIAL			40			21	92%

Abbreviations: CONV: conventional 2D cine acquisition; 2-SA: 3D-cine acquisition of two overlapping slabs in the short-axis (SA) direction; 1-SA: 3D-cine acquisition of one thick slab in the SA direction; 2-AXIAL: 3D-cine acquisition of two overlapping slabs in the axial direction with semi-isotropic resolution; 1-AXIAL: 3D-cine acquisition of one thick slab in the axial direction. Shown scan times include recovery time inbetween repeated breath-holds. CNR: contrast-to-noise ratio; SNR: signal-to-noise ratio.
