Predicting Coronary Artery Calcium Severity based on Non-Contrast Cardiac CT images using Deep Learning

arXiv — cs.CV•Wednesday, November 12, 2025 at 5:00:00 AM
PositiveArtificial Intelligence
The recent study on predicting coronary artery calcium (CAC) severity using deep learning highlights a significant advancement in cardiovascular diagnostics. By employing a convolutional neural network (CNN) model on a dataset of 68 patient scans, researchers demonstrated a high performance with a Cohen's kappa of 0.962, indicating strong agreement with traditional semi-automated scoring methods. The model misclassified 32 cases, primarily overestimating CAC in 26 instances, yet its overall accuracy of 96.5% suggests promising generalizability. This innovation is particularly relevant as cardiovascular diseases remain a leading cause of mortality globally, and efficient risk stratification tools like CAC scoring are essential for timely interventions. The study's findings could lead to more accessible and quicker assessments in clinical settings, ultimately enhancing patient care and outcomes in cardiovascular health.

Rethinking Saliency Maps: A Cognitive Human Aligned Taxonomy and Evaluation Framework for Explanations
NeutralArtificial Intelligence
Saliency maps are essential tools for providing visual explanations in deep learning, yet there is a significant lack of consensus on their purpose and alignment with user queries. This ambiguity complicates the evaluation and practical application of explanation methods. The introduction of the Reference-Frame × Granularity (RFxG) taxonomy aims to address this issue by categorizing saliency explanations based on two axes: Reference-Frame and Granularity, highlighting limitations in current evaluation metrics.
