Automated lung nodule triage modeled to cut costs by targeting discordant reads

Among 243 thoracic CTs, 10% had incorrect pulmonary nodule management recommendations (more common from general radiologists). Automated triage triggering review when AI missed a reported nodule was the most cost-saving pathway per corrected error.

• Errors in nodule management were significantly more frequent in reports by general radiologists (χ² ~11.0, P<.05).
• Triage pathway that selected cases where the radiologist identified a nodule but automated assessment did not yielded the greatest cost savings.
• The study modeled pathways retrospectively; prospective real-world validation is needed.
