Implication

Diagnostic accuracy study reveals adding xenon-133 ventilation imaging to perfusion scans improves specificity for pulmonary embolism, indicating superior diagnostic value.

Key Points

To define the diagnostic role and value of adding xenon-133 ventilation studies to perfusion scintigraphy for detecting pulmonary embolism.
Reviewed angiographic, scintigraphic, and clinical records of 40 patients (N=40).
Two independent observers evaluated perfusion scans alone and later re-evaluated them paired with xenon-133 ventilation studies.
Inclusion of xenon-133 ventilation studies significantly improved overall diagnostic accuracy (p < 0.05).
Combined ventilation-perfusion imaging yielded slightly higher sensitivity and significantly greater specificity (p < 0.05) for pulmonary embolism than perfusion imaging alone.
