From: Diffusion-weighted magnetic resonance imaging using a preclinical 1 T PET/MRI in healthy and tumor-bearing rats

Tumor Day Voltumor (mm3) Volvital (mm3) Viable tumor (%)
2 13 1532 1106 72
20 3821 2151 56
3 10 0143 130 90
16 1028 899 87

  1. Voltumor = volume of the whole tumor measured by MRI; Volvital = FDG-avid tumor tissue defined as above a 45% threshold of the maximum tumor uptake
