Figure 4From: Dual tracer evaluation of dynamic changes in intratumoral hypoxic and proliferative states after radiotherapy of human head and neck cancer xenografts using radiolabeled FMISO and FLT Quantitative analysis of intratumoral (A) 18 F-FMISO and (B) 3 H-FLT uptake levels by ARG and (C) regression analysis of the uptake levels of 18 F-FMISO and 3 H-FLT. Data are expressed as mean ± SD. *p < 0.01 and **p < 0.0001 for both Control vs Treat-10 Gy and Control vs Treat-20 Gy. †p < 0.001, 6 hrs vs day 7 for each group radiation-treated with 10 and 20 Gy.Back to article page
