Combining AI with radiologists substantially improves detection of pulmonary embolism (PE) on CT pulmonary angiography (CTPA) scans, new research shows.
Key Details
- 1Researchers retrospectively analyzed 32,500 CTPA exams from over 29,000 adults (2021-2023).
- 2AI and radiologists agreed on PE diagnosis in 97.8% of cases.
- 385% of positive PE cases were flagged by AI and confirmed by radiologists; 15% were found only by radiologists.
- 4Radiologists were correct in 88.7% of the disagreements; AI in 11.3%.
- 5AI-informed radiologists achieved 99.2% sensitivity for PE detection.
- 6Concordance was highest for acute and central emboli, which have the most clinical urgency.
