Figure 6. — Correlation analysis for ⁶⁸Ga-FAPI-04 uptake and pulmonary function test (PFT). (A) Timeline for positron emission tomography (PET)/computed tomography (CT) and PFT: the first PFT was conducted within no more than 1 month from PET/CT scan. The time interval between the two PFT measurements was approximately 4–20 months. (B) Correlation analysis between standard uptake value (SUV) for ⁶⁸Ga-FAPI-04 (SUVtotal and SUVmean) and PFT (baseline Dl_CO and FVC). (C) Correlation analysis between ⁶⁸Ga-FAPI-04 (SUVtotal and SUVmean) uptake and changes in PFT (change from baseline in Dl_CO and FVC). Linear regression (r) and linear regression lines are plotted. P < 0.05 was considered statistically significant. FAPI = fibroblast activation protein inhibitors.
