Emphysema severity assessment: ESI test is now validated

The server-side (real time) software developed for ESI calculation is now validated.

The ESI methodology was implemented to provide a simple and effective tool for the assessment of emphysema severity in smokers, ex-smokers patients with COPD.

The web-based application available here at www.emphysema.app was used to calculate the ESI (Emphysema Severity Index) in a population of 5930 subjects (smokers, ex-smokers, patients with COPD).

The ESI values were compared with the CT-based metrics obtained by advanced software (CT images analysis).

The results are now published in Respiratory Research:
