Fig. 2

A Coronal section of thoracic cavity on a baseline PET-CT scan. Red outlined area is the region of interest (ROI) where all pixels have standardised uptake value (SUV) of 2.0 or greater. Maximum standardised uptake value (SUVmax) is defined as the hottest pixel within the ROI. SUVmean is defined as the average SUV of all pixels within the ROI. Dark blue outlined area represents a cavity within consolidated lung tissue. Cavity diameter (cm) was the widest measurement of the cavity on CT imaging. B 3-D of a volume of interest (VOI, cm3) of a single lesion where the SUV of voxels is 2.0 or greater. Total Metabolic Volume (TMV, cm3) is defined as the summation of all VOIs within a single scan. Total lesion glycolysis (TLG) is the product of metabolic volume in cm3 and SUVmean and is expressed without units.
