3D cardiac cine MRI provides consistent data for complete LV analysis in a single scan. As this acquisition is too long for a breathhold, respiratory gating is typically applied.

The aim of this study is to investigate whether respiratory gating is also required for 3D cardiac cine MRI when using a Stack-of-Stars acquisition.

Ungated and Self-Gated reconstructions are compared visually and for LV function parameters.

As no motion artifacts are apparent even in the ungated cine data, and LV function results are comparable to the gated images, ungated reconstruction seems to be feasible for LV analysis.
