(A) Radioactivity accumulation in the lungs of mice in the CS and Air groups at 45 and 90 min after injection of 18F-IPFP. (B) Radioactivity accumulation ratio (L/B, lung to blood; L/H, lung to heart, L/M, lung to muscle) for the CS and Air groups at 45 min after injection of 18F-IPFP. *p < 0.05 vs corresponding Air groups calculated by unpaired t-test with Welch’s correction.
