How Analyze was Used
“An upper and lower attenuation range for fat was set at − 200 and − 20 Hounsfield units, respectively [Jackson and Thomas 2004]. The CT images were then thresholded at this fixed attenuation range using Analyze 7.0…, such that all pixels sampled afterwards were those representing adipose tissue.”
