Radioclinical associations of automated lung volumes measurements.

Measured lung volumes for the automated process of (A): Ground-glass opacities; (B) Restricted Normally Aerated and for (C) the ratio of Ground-glass opacities and Restricted Normally Aerated volumes for those with class 3,4 and 6 maximal respiratory severity during the 7 days following the CT scan. The association between the automated measured lung volumes and the maximal clinical severity score was statistically significantly different for the restricted normally aerated (p = 0.0097) volumes and for the ratio of ground-glass opacities/restricted normally aerated volumes (p = 0.027). No patients in our cohort were classified as 1, 2, 5 or 7 on this scale.
