Study of 18F-Fibroblast Activation Protein Inhibitor 18F-FAPI-74 PETCT Scans in Adults with Pulmonary Tuberculosis to Detect Lung Fibrosis

What this Trial Is About

Researchers are evaluating the use of 18F-Fibroblast Activation Protein Inhibitor 18F-FAPI-74 positron emission tomography PET as a noninvasive biomarker to assess lung disease and fibrosis in patients with active tuberculosis TB. The study focuses on microbiologically confirmed TB patients to determine if 18F-FAPI-74 PET can detect fibrosis in TB lesions with high sensitivity. Participants will receive a single intravenous dose of 18F-FAPI-74 followed by a PETCT scan performed either during the first six weeks of TB treatment or within six weeks after completing six months of TB treatment. Some patients may have a second PETCT scan after treatment completion to compare findings. This process allows assessment of fibrosis at different stages of TB treatment. During the study, participants will undergo whole-body PET scans after injection of 18F-FAPI-74, with imaging correlated to sites of TB lesions identified on computed tomography CT. Researchers will measure the uptake of 18F-FAPI-74 using standardized uptake values within one hour. Participants will provide informed consent and comply with scheduled visits and procedures. Safety and laboratory tests will be monitored throughout the study.
