Detection Of Low Attenuation Area With Low-Dose Spiral Ct On The Health Check-Up - Correlation Between Automated Analysis And Pulmonary Function

PURPOSE: According to diagnoses of pulmonary emphysema, many studies have suggested a relationship between the degree of low attenuation area (LAA) and pulmonary function. We developed an automated analysis system of LAA on Low-dose spiral CT (LDCT). The purpose of this study is to determine the correlation between LAA on LDCT and pulmonary function.
