[18F] fluoromisonidazole ([18F]FMISO) PET-CT demonstrates increased tracer uptake within TB lesions. (A) [18F]FMISO PET-CT images. Transverse, coronal and sagittal slices through the [18F]FMISO target-to-background (TBR) and CT images of Patient 2. Top row, CT images show consolidation and a pulmonary cavity in the right upper lobe with a smaller, non-cavitating lesion in the left lung. Middle row, [18F]FMISO TBR map demonstrates intense uptake of tracer in the right upper lobe lesion and the liver, the site of metabolism of [18F]FMISO. Bottom row, coregistered CT and TBR images. (B) TBR values greater than unity were found for at least one lesion in all patients (each individual bar represents one region of interest, ROI).
