Increased 68Ga-FAPI Uptake in the Pulmonary Cryptococcus and the Postradiotherapy Inflammation

A 51-year-old man, previously treated for nasopharyngeal carcinoma, presented a newly detected pulmonary nodule. This patient underwent 18 F-FDG and 68 Ga-FAPI PET/CT to detect tumor recurrence under the prospective study NCT04416165. Both 18 F-FDG and 68 Ga-FAPI PET/CT showed intense uptake in a pulmonary nodule in the right lower lobe. In addition, 68 Ga-FAPI PET/CT demonstrated increased uptake in the nasopharynx that previously treated with...
