Key result
Thoracic CT values and pleural fluid to blood CT value ratios accurately differentiated exudative from transudative pleural effusions, yielding AUCs of 0.85 and 0.86, respectively.
Why the study?
Data assessing the accuracy of thoracic CT for separating transudative from exudative effusions are limited.
Does thoracic CT value and PF to blood CT value ratio accurately differentiate transudative from exudative pleural effusion in patients with pleural effusion?
Cohort (n=404)
Single-blind (investigators measuring CT values)

Thoracic CT attenuation values and the pleural fluid to blood CT value ratio can accurately differentiate transudative from exudative pleural effusions, potentially reducing the need for unnecessary diagnostic thoracentesis.
Zhang et al. (2024) conducted a cohort in Pleural effusion (n=404). Thoracic CT scan (CT value and PF to blood CT value ratio) vs. Transudative vs Exudative effusions (Light's criteria) was evaluated on Area under the curve (AUC) for CT value (cut-off 10.81 HU) to differentiate transudative from exudative pleural effusions (AUC 0.85, 95% CI 0.80-0.91). Thoracic CT values and pleural fluid to blood CT value ratios accurately differentiated exudative from transudative pleural effusions, yielding AUCs of 0.85 and 0.86, respectively.
