CT scan and ultrasound comparative assessment of PEEP-induced lung aeration changes in ARDS

CT-scan quantitative analysis (qCT) represents the gold standard to assess lung aeration and recruitment in ARDS patients. Lung ultrasound (LUS) has been proposed as a bedside nonirradiating alternative to assess lung recruitability, identifying patients who may benefit from higher PEEP levels. We compared the two methods in the assessment of PEEP-induced lung aeration changes.
