The AI model achieved an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.83 (95% CI:0.81-0.85) in external validation, outperforming experienced physicians (0.80, p=0.02) and individual biomarkers like ischemic TPD (0.79, p<0.001) and MFR (0.75, p<0.001). This demonstrates superior diagnostic accuracy and reliability.
Performance was consistent across diverse patient subgroups (sex, BMI, age), highlighting the model's robustness and generalizability. Tracer-specific normal limits and dedicated kinetic models ensured compatible quantitative values across different PET tracers.
Our approach integrates key PET-CT parameters including calcium burden, perfusion, MBF, and functional metrics into a unified assessment. Unlike traditional methods, the AI model processes multidimensional data as continuous variables, providing a probability-based assessment without arbitrary thresholds.
The model leverages Shapley Additive Explanations (SHAP) values to highlight the most influential factors driving predictions (ischemic TPD, stress TPD, CAC, MFR), ensuring transparency and enabling physicians to validate case-specific diagnostic factors. This 'explainable AI' (XAI) approach fosters trust and clinical adoption.
This multicenter, externally validated AI model improves PET MPI diagnostic accuracy, offering automated and interpretable predictions for CAD diagnosis. It enhances clinical workflows by providing quantitative, objective insights and actionable decision support.
While robust, the study has limitations: it's retrospective, focused on a specific CAD definition, and did not assess physiological significance (FFR/iFR) or microvascular dysfunction. Future prospective studies are needed for regulatory approval and real-world translation.

Case Study: Precision in Borderline Cases
A patient presented with borderline ischemic TPD and clinician-assigned stress scores, typically leading to uncertainty. Traditional assessment indicated an abnormal scan, suggesting possible CAD.
However, the AI model correctly integrated normal MFR and stress MBF with other parameters to accurately rule out obstructive CAD, aligning with the patient's actual condition. This averted unnecessary invasive procedures and demonstrated the AI's ability to discern subtle patterns missed by isolated metrics.
This case highlights the AI model's power in leveraging integrated biomarkers to provide precise, patient-specific predictions, enhancing diagnostic confidence and optimizing patient management in complex scenarios.
