Table 1 Terminology regarding the dimensions and components of CMR velocity acquisitions.
Data acquisition method | Abbreviated description | Comment |
|---|---|---|
3 dimensional, 3 directionally encoded, cine velocity acquisition | 3D cine phase contrast, 3D cine velocity acquisition (more explicit) or 4D velocity acquisition (conveniently concise) | This is 'comprehensive' in the sense that all 3 directional components of velocity are measured with respect to all 3 spatial dimensions and the time course over the cardiac cycle. |
2 dimensional, 1 directionally encoded (usually through-plane), cine velocity acquisition | 2D cine phase contrast, 2D cine velocity mapping | Allows calculations of volume flow through a plane that transects a vessel. |
