This shows coronal (left), sagittal (middle) and transverse (right) views of different CT images with the auto-delineated metabolic lesion volume as an overlay and a scatterplot representing the CT density (Y axis, HU) and the PET uptake intensity (X axis; Z-score) of the voxels held within the lung mask a Lesion-free lungs from control participant. bd Dx, M1 and M6 PET-CT scans for PTB patients. b Cured patient with an improved scan response and moderate uptake still present at M6. c Cured patient, with a resolved scan response. Only minimal intensity residual lesions and thin-walled cavities still present at M6. d Failed treatment case, with a mixed scan response pattern and multiple lesions with very high uptake present at M6
