Image-based deep learning models show high accuracy for aortic dissection segmentation and diagnosis compared to clinicians.
A systematic review and meta-analysis synthesized evidence from 48 studies assessing image-based deep learning models for aortic dissection. The primary focus was on segmentation accuracy and diagnostic performance compared to clinician assessments. No specific population or setting details were reported for the individual studies included in this analysis.
In segmentation tasks, deep learning models achieved a Dice coefficient of 89.2% ± 4.4% for false lumen, 90.8% ± 3.4% for true lumen, and 91.7% ± 6.1% for the entire aorta. Diagnostic performance varied by imaging modality. CT-based models showed a sensitivity of 0.94 (95% CI: 0.89–0.96) and specificity of 0.92 (95% CI: 0.88–0.95). ECG-based models yielded a sensitivity of 0.85 (95% CI: 0.79–0.89) and specificity of 0.90 (95% CI: 0.87–0.92).
CTA-based models demonstrated a sensitivity of 0.94 (95% CI: 0.90–0.96) and specificity of 0.95 (95% CI: 0.91–0.98). Clinicians exhibited a sensitivity of 0.79 (95% CI: 0.65–0.89) and specificity of 0.95 (95% CI: 0.88–0.94). Adverse events, tolerability, and discontinuations were not reported. The analysis included 48 studies, but the specific patient population and clinical settings were not reported.
Key limitations include the need for multicenter validation, seamless integration into clinical workflows, and enhanced model generalizability to facilitate broader adoption. These models performed comparably to or better than clinicians in diagnostic tasks. The evidence supports their potential role as clinical assistive tools, though further validation is required before widespread clinical reliance.
