Previous
DTI studies on infarcted LV
myocardium structure usually explored myocardial fiber orientation,
diffusivity or diffusion anisotropies. In current study, superquadric glyphs
were applied on infarcted porcine model. Diffusion tensor shape and laminar
sheet structure were examined for the first time to describe infarcted
myocardium structural alteration. Results show that significant change of
diffusion tensor shape occurred in both infarct and adjacent regions.
Apparent alteration of laminar sheet structure was observed in adjacent and
remote regions. The current study demonstrates the ability of superquadric
glyphs to detect myocardium structural degeneration and provides supplemental
information for infarcted heart remodeling.
