A large study confirms that combining radiologists with FDA-cleared AI significantly improves pulmonary embolism detection on CTPA.
Key Details
- 1Study analyzed 32,501 CT pulmonary angiography (CTPA) exams in 29,492 patients at Northwell Health.
- 2Radiologist-AI agreement was 97.8% overall: 98.2% for AI-negative and 93.8% for AI-positive cases.
- 3AI-informed radiologists achieved 99.2% sensitivity for PE; AI alone missed clinically relevant cases detected by radiologists.
- 4Of all PE-positive cases, 84% were detected by both, 15% by radiologists only, and 0.8% by AI only.
- 5Radiologists' interpretations were confirmed in 88.7% of discordant cases after adjudication.
- 6Concordance was higher for acute/central PEs compared to chronic/peripheral emboli.
Why It Matters
This large-scale real-world evidence reinforces radiologists' essential role and shows that AI tools add value through collaboration rather than automation alone, especially in life-threatening clinical scenarios. These findings help guide best practice adoption for AI integration in routine emergency radiology workflows.
