Treatment effect on tumor volumes, cell proliferation and overall survival. (a) Representative T2w-MRI and [18F]-FLT images for the three different groups of rats before and after treatments. From the top to the bottom: T2w-MRI before treatment (D21); T2w-MRI one day after treatments (D24); [18F]-FLT images at D24 and lastly, T2w-MRI at D28 and D42. Quantitative analyzes of SUV-[18F]-FLT one day after treatments in (b) striatal metastases and (c) cortical metastases. Mean ± SD, n = 7 for Control and RT groups and n = 6 for HIGRT group, *p < 0.05 and **p < 0.01 versus Control group and #p < 0.05 versus RT group. Quantitative analyzes of tumor volume before and after treatment in (d) striatal metastases and (e) cortical metastases (TMT: treatments). Mean ± SD, n = 7 for Control and RT groups and n = 6 for HIGRT group, ***p < 0.001 versus Control group and ###p < 0.001 versus RT group. (f) Kaplan–Meier curves of survival, n = 6 for Control, n = 7 for RT and n = 5 for HIGRT groups. **p < 0.01 and ***p < 0.001 versus Control group and ##p < 0.01 versus RT group.
