Figure 1 :Maximum intensity projection images (MIP) of baseline (a) and follow-up (b) FDG PET study in a case of FUO due to tuberculosis. Baseline study (a) shows intense FDG uptake in mediastinal lymph nodes, L2 vertebra and right sacro-iliac joint (arrows). Physiological uptake of FDG is also noted in the brain, myocardium, breasts, liver, bone marrow, bowel and urinary tract. Follow-up study after 8 weeks of ATT (b) shows FDG uptake in the previously involved sites. However, there is a significant reduction in FDG accumulation in the previously diseased sites
