FDG-PET were quantitatively analyzed using SUVmax. SUVmax corresponds to the maximum Standardized Uptake Value (SUV) in a voxel within a circular region of interest drawn manually for each site showing FDG uptake. SUVmax was measured on the most active lymph node in each lymph node site. Concerning organ FDG uptake, only SUVmax of the most active organ was described. Percentage change in SUVmax between serial FDG-PET/CT (or DeltaSUVmax) was calculated as follows: %DSUVmax = (SUVmaxT0 - SUVmaxT2) / SUVmaxT0 x 100 (with T0 the baseline FDG-PET/CT and T2 either PET2 or PET3). DeltaSUVmax was considered significant when ≥ 20%. In our analysis, the PET2 performed after 2 months of TB treatment was compared to the baseline FDG-PET/CT (PET1). PET3, performed at the end of TB treatment, was compared to PET1.
