Objective:

To describe the implementation and workflow of an AI-based coronary artery calcium (CAC) scoring system at Wonkwang University Hospital, highlighting its significance in improving diagnostic efficiency.

Key Findings:

AI-generated CAC reports were typically available within 10 minutes of CT image upload.
High agreement between AI-based CAC scoring and manual reference standards for continuous scores and categorical grading, with specific metrics to be included.
False-positive and false-negative detections persisted, particularly related to noncoronary calcifications and motion artifacts, impacting clinical decision-making.

Interpretation:

Radiologist oversight remains essential, especially in patients with extensive calcification or complex coronary anatomy, to ensure accurate diagnosis and treatment.

Limitations:

Lack of detailed audit methods, sample size, and patient characteristics may limit the generalizability of findings.
False-positive and false-negative detections were noted, particularly in patients with high CAC burden or structural coronary abnormalities, which could affect patient management.

Conclusion:

The editorial highlights the benefits of AI in reducing manual tasks and improving efficiency but emphasizes the critical need for radiologist verification to ensure patient safety.
