Percentage change of quantitative measurements between before CRT and during CRT at a dose of 40 Gy
| CR group (n = 11) | Non-CR group (n = 6) | P-value | |
|---|---|---|---|
| Maximum diameter (%) | 40.2 ± 23.8 | 29.4 ± 17.2 | 0.347 |
| ADC (%) | 73.3 ± 38.5 | 34.4 ± 20.7 | 0.038* |
| D (%) | 56.0 ± 30.4 | 28.2 ± 16.8 | 0.057 |
| D* (%) | 2.6 ± 1.3 | 1.5 ± 0.8 | 0.093 |
| f (%) | 18.9 ± 9.8 | 10.3 ± 12.1 | 0.070 |

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.
