RESPECTED ‐Long: A Retrospective Longitudinal Cross‐Sectional Single Centre Study Finds Increasing Emergency Department CT ‐Pulmonary Angiography Rates Over a Decade With Sustained Pulmonary Embolism ( PE ) Diagnostic Yield

Key Points

• Diagnostic yield for pulmonary embolism remains sustained despite increased CTPA rates over the last decade.
• CTPA use increased significantly, yet larger vessel PE diagnoses showed a marked decline alongside stable small PE rates.
• Younger women are being investigated more frequently for PE, with a notably low diagnostic yield of 5.6%.
• The findings suggest that the diagnostic discrimination of CTPA remains effective even with increased usage.
