Fig. 5: Qualitative examples of failure modes for the ScarElastic framework.
From: ScarElastic: continuous elasticity field modeling for myocardial scar delineation in LGE-CMR
Each row represents a distinct challenge: A Thin subendocardial scar: the model under-segments an extremely thin scar (yellow arrow), likely due to the smoothness regularization penalizing high-frequency details. B Cardiac apex slice: in a slice near the apex, the model generates a false positive (yellow arrow) due to partial volume effects and the complex, thinning myocardium. C Severe motion artifacts: significant motion artifacts in the input LGE-CMR lead to a noisy and inaccurate elasticity field prediction.
