Computation of the differential properties of the left ventricular surface using cine MRI allows for the representation of LV shape in both static and dynamic manners.
This study presents a novel analytic approach using cine MRI to quantify and represent the 3D surface shape of the left ventricle, which may aid in assessing regional functional abnormalities in diverse cardiac diseases.
May aid regional LV assessment in cardiac disease; leaves open prospective validation before clinical adoption.
Left ventricular functional abnormalities are postulated to be associated with regional modification of surface curvature. This study describes the computation of the differential properties of the LV surface via an analytic approach using local surface fitting. Quantification was implemented with cine magnetic resonance imaging (MRI), which was used as the source to derive 3D wire-frame models and the related shape descriptors. Based on these shape descriptors, the shape of LV could be represented in both static and dynamic manners. These may have implications for diverse cardiac diseases.

Zhong et al. (2007) studied Left ventricular functional abnormalities. Computation of differential properties of the LV surface via local surface fitting using cine MRI was evaluated on Quantification of LV surface shape descriptors.
