The precise quantification of cardiac involvement in sarcoidosis is a critical aspect of patient management and prognosis, and automated segmentation algorithms are emerging as powerful tools to achieve this goal [1].
These advanced computational techniques, particularly those leveraging deep learning, offer substantial advantages over traditional manual segmentation methods, enhancing accuracy, reproducibility, and efficiency in assessing myocardial inflammation and fibrosis, which are hallmarks of cardiac sarcoidosis [1].
Machine learning algorithms are increasingly being applied to delineate myocardial scar tissue in cardiac magnetic resonance imaging (CMR), enabling accurate scar burden quantification and differentiation between transmural and non-transmural scar, vital for risk stratification in various cardiomyopathies, including sarcoidosis [2].
The standardization of scar quantification through these advanced methods promises to improve the reliability of diagnostic and prognostic assessments [2].
A robust deep learning-based framework has been developed for the automated segmentation of the left ventricle from cardiac MRI, demonstrating high accuracy and robustness [3].
