Quantitative measurements during CRT at a dose of 20 Gy
| CR group (n = 11) | Non-CR group (n = 6) | P-value | |
|---|---|---|---|
| Maximum diameter (mm) | 37.7 ± 19.3 | 52.3 ± 11.8 | 0.114 |
| ADC (×10−3 mm2/s) | 1.28 ± 0.25 | 1.16 ± 0.17 | 0.317 |
| D (×10−3 mm2/s) | 1.03 ± 0.18 | 0.99 ± 0.12 | 0.623 |
| D* (×10−3 mm2/s) | 5.31 ± 0.06 | 5.29 ± 0.04 | 0.617 |
| f (%) | 16.2 ± 1.2 | 15.9 ± 0.8 | 0.636 |
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.
