### T.3.1 Landmark Based Wall Motion Regions

Figure T.3-1. Landmark Based Wall Motion Regions

To compare the quantitative results with those provided by the usual visual interpretation, the left ventricular boundary is divided into 5 anatomical regions, denoted:

- Anterobasal.

- Anterolateral.

- Posterobasal.

- Diaphragmatic.

- Apical.
