FIG. 1.

ROIs selected from various tissues within the same CT section: (a) fat, (b) mesothelioma, (c) ascending aorta, (d) pulmonary artery with artifact, (e) pulmonary artery, (f) descending aorta, (g) mesothelioma contour by radiologist, and (h) muscle.

FIG. 2.

The distributions of HU values for the 13 tissue types across all 28 CT scans. Extensive overlap exists among mesothelioma, muscle, and liver.

Image of FIG. 3.
FIG. 3.

The distributions of HU values of mesothelioma, muscle, and liver for three different scanner and reconstruction filter/kernel combinations.

Tables
