The aim of CPAP study is to test the effect of applying positive airway pressure (PAP) during CT acquisition to improve segmentation, particularly at end-expiration.
CPAP DataBase is a register built for this study and records data on CT acquisitions in inspiration and expiration with 4 PAP protocols. Were recorded prospectively and compared to baseline inspiratory acquisitions in 20 patients. The 4 protocols explored differences between devices (flow vs. turbine), exposures (within seconds vs. 15-min) and pressure levels (10 vs. 14 cmH2O).
CT scans were acquired with a 320-detector row, 0.5 mm slice thickness, at intervals of 0.4 mm, 80 × 0.5 mm collimator, tube voltage of 100 kVp, and tube current adapted for sex and body mass index.

Database Version 3, dated December 7, 2023, comprises a total of 96 pulmonary nodules. It includes all the nodules present in the previous versions (Version 1 and 2), thereby incorporating the data from the earlier database and including the diagnosis and scan’s acquisition parameters.
