Implication

Low-probability V/Q criteria lack validated sensitivity/specificity; leaves open reliable use across prevalence and supports revised categorization standards.

Key Points

To evaluate the diagnostic validity and methodological limitations of standard criteria used to categorize ventilation-perfusion lung scans as low probability for pulmonary embolism.
Assessed classic diagnostic criteria (Biello and McNeil) used to stratify ventilation-perfusion lung scan findings into probability categories.
Analyzed the methodological reliance on predictive values versus prevalence-independent sensitivity and specificity relative to pulmonary angiography reference standards.
Classic interpretive criteria for low-probability lung scans lack established sensitivity and specificity independent of underlying disease prevalence.
Reporting predictive values without true sensitivity and specificity creates substantial variability across differing clinical settings and disease prevalence levels.
