  • * P < 0.09 vs. contralateral tissue.

  • P < 0.005 vs. contralateral tissue.

  • P < 0.05 vs. deoxyglucose tumor-to-tissue ratio.

  • § Data are from rats implanted with C6 tumors.

  • Data are mean ± SD (C6 tumors: n = 6 for glucose use, n = 7 for acetate uptake; U-373 tumors: n = 4 per group for glucose use and acetate uptake).
