Fig. 2From: Computer-aided analysis in evaluation and grading of interstitial lung diseases in correlation with CT-based visual scoring and pulmonary function testsFemale patient 42 years old, FEV1 72%. a Axial HRCT image shows GGO seen posteriorly at lower lung zones. CT-based visual scoring = 20. b CT attenuation Histogram. Kurtosis 5.013, skewness 1.744, and whole lung density − 751. This was a case of mild ILD according to FEV1 results which are correlated with low CT-based visual score and mild reduced lung density at CT attenuation histogramBack to article page
