Percentage change of quantitative measurements between before CRT and during CRT at a dose of 20 Gy
| CR group (n = 11) | Non-CR group (n = 6) | P-value | |
|---|---|---|---|
| Maximum diameter (%) | 15.3 ± 18.8 | 7.6 ± 9.6 | 0.365 |
| ADC (%) | 39.0 ± 16.9 | 14.1 ± 20.5 | 0.016* |
| D (%) | 37.4 ± 23.7 | 13.5 ± 9.7 | 0.039* |
| D* (%) | 1.7 ± 1.0 | 0.7 ± 0.5 | 0.039* |
| f (%) | 12.7 ± 7.3 | 5.2 ± 2.5 | 0.036* |

Significant difference was found between CR and non-CR group. Values are the mean ± 1 standard deviation. CR, complete remission; CRT, chemoradiotherapy; ADC, apparent diffusion coefficient; D, true diffusion coefficient; D*, perfusion-related pseudo-diffusion coefficient; f, perfusion fraction.
