dc.description.abstract | We propose a fully three-dimensional methodology
for the computation of myocardial non-viable tissue transmurality
in contrast enhanced magnetic resonance images. The outcome
is a continuous map defined within the myocardium where not
only current state-of-the-art measures of transmurality can be
calculated, but also information on the location of non-viable
tissue is preserved. The computation is done by means of a
partial differential equation framework we have called Multi-
Stencil Streamline Fast Marching (MSSFM). Using it, the myocardial
and scarred tissue thickness is simultaneously computed.
Experimental results show that the proposed 3D method allows
for the computation of transmurality in myocardial regions where
current 2D methods are not able to as conceived, and it also
provides more robust and accurate results in situations where the
assumptions on which current 2D methods are based —i.e., there
is a visible endocardial contour and its corresponding epicardial
points lie on the same slice—, are not met. | es |
