Quantitative measurements before CRT
| CR group (n = 11) | Non-CR group (n = 6) | P-value | |
|---|---|---|---|
| Maximum diameter (mm) | 44.6 ± 19.1 | 56.8 ± 13.1 | 0.186 |
| ADC (×10−3 mm2/s) | 0.93 ± 0.18 | 1.03 ± 0.11 | 0.226 |
| D (×10−3 mm2/s) | 0.76 ± 0.18 | 0.87 ± 0.10 | 0.186 |
| D* (×10−3 mm2/s) | 5.22 ± 0.06 | 5.26 ± 0.03 | 0.187 |
| f (%) | 14.4 ± 1.2 | 15.1 ± 0.6 | 0.174 |
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.
