This study aims to validate a semi-automatized method to quantify cyclic hyperinflation on CT-scan of ARDS patients.
The gold standard will be cyclic hyperinflation assessed on the same CT scan, using manual segmentation of the lung.

| ARDS patients | Other | The patient will be installed on the scanner bed. Two series of tomographic sections will be acquired: one during an expiratory break, the other during an inspiratory pause. cyclic hyperinflation measured by semi-automatic segmentation and by manual segmentation |
| Measure | Description | Time Frame |
|---|---|---|
| cyclic hyperinflation measured by manual segmentation | Bias and precision of semi-automated measure will be assessed with the Bland and Altman Technique, using cyclic hyperinflation by manual segmentation as a reference | 2 hours after inclusion |
| cyclic hyperinflation measured by semi-automated segmentation | Bias and precision of semi-automated measure will be assessed with the Bland and Altman Technique, using cyclic hyperinflation by manual segmentation as a reference | 2 hours after inclusion |
| Measure | Description | Time Frame |
|---|---|---|
| prevalence of cyclic hyperinflation on CT scan | cyclic hyperinflation assessed by manual segmentation on CT scan | 2 hours after inclusion |
| area under receiver operating characteristic (ROC) curve of respiratory system driving pressure to detect cyclic hyperinflation assessed by manual segmentation |
