Fig. 2From: 18F-Fluorodeoxyglucose positron emission tomography may not visualize radiation pneumonitisCoronal (left) and cross-sectional scans of FDG uptake in the right lungs of rats in the control, radiotherapy (RT)-only, lipopolysaccharide (LPS)-only, and RT+LPS groups at 7 weeks after RT. No significant FDG uptake was observed in the control (a) or RT-only group (b), but FDG uptake clearly increased in the LPS-only (c) and RT+LPS (d) groupsBack to article page
