Materials and Methods Eighteen HIV-positive patients, 18 years old or more, with extra pulmonary TB were enrolled after providing written informed consent. Baseline FDG-PET/CT was performed before or as soon as possible after initiating TB treatment, followed by FDG-PET/CT after 2 months of TB treatment and at the end of TB treatment according to guidelines (6 months/9-12 months if bone or CNS TB). However, real duration of treatment was left at the discretion of physician, blinded to the results of second and third FDG-PET/CT.
