Quantitative measurements during CRT at a dose of 40 Gy
| CR group (n = 11) | Non-CR group (n = 6) | P-value | |
|---|---|---|---|
| Maximum diameter (mm) | 27.5 ± 18.6 | 40.0 ± 11.7 | 0.158 |
| ADC (×10−3 mm2/s) | 1.58 ± 0.31 | 1.37 ± 0.16 | 0.160 |
| D (×10−3 mm2/s) | 1.16 ± 0.21 | 1.11 ± 0.12 | 0.567 |
| D* (×10−3 mm2/s) | 5.35 ± 0.07 | 5.34 ± 0.04 | 0.563 |
| f (%) | 17.1 ± 1.4 | 16.7 ± 0.8 | 0.551 |
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.
