Results for patient 1, a 37-y-old man with symptomatic sarcoidosis. (a) A baseline ¹⁸F-FDG PET image revealed increased activity in mediastinal lymph nodes, lung parenchyma, liver, and spleen. (b) On the follow-up examination performed at 1 month, PET-CT showed significantly less activity in the mediastinal lymph nodes, liver, and spleen. However, his symptoms persisted but were less severe. (c) On the follow-up examination performed at 2 months, all abnormal uptakes were not apparent.
