Lung tissue SUV of radiation pneumonitis group prior to and following radiotherapy.
| SUV of lung tissue at different exposures | Prior to radiotherapy | Standard deviation | Following radiotherapy | Standard deviation | P-value |
|---|---|---|---|---|---|
| ≥60 Gy | 0.68 | 0.042 | 1.47 | 0.285 | 0.025 |
| 35 to ≤59.9 Gy | 0.44 | 0.026 | 0.97 | 0.154 | 0.015 |
| 15 to ≤34.9 Gy | 0.45 | 0.021 | 0.65 | 0.120 | 6.051 |
| 5 to ≤14.9 Gy | 0.41 | 0.018 | 0.58 | 0.058 | 4.025 |
| ≤5 Gy | 0.39 | 0.022 | 0.44 | 0.036 | 1.337 |
Exposure doses of different lung tissues were calculated by the isodose curve. SUV, standardized uptake value.
