AB We propose a fully three-dimensional methodologyfor the computation of myocardial non-viable tissue transmuralityin contrast enhanced magnetic resonance images. The outcomeis a continuous map defined within the myocardium where notonly current state-of-the-art measures of transmurality can becalculated, but also information on the location of non-viabletissue is preserved. The computation is done by means of apartial differential equation framework we have called Multi-Stencil Streamline Fast Marching (MSSFM). Using it, the myocardialand scarred tissue thickness is simultaneously computed.Experimental results show that the proposed 3D method allowsfor the computation of transmurality in myocardial regions wherecurrent 2D methods are not able to as conceived, and it alsoprovides more robust and accurate results in situations where theassumptions on which current 2D methods are based —i.e., thereis a visible endocardial contour and its corresponding epicardialpoints lie on the same slice—, are not met.
