Case 21. A 59-year-old woman with GBM in the right temporal lobe (tumor volume, 79.6 cm3). PET images of 62Cu-ATSM (A), FDG (B), and MET (C) are shown; the 62Cu-ATSM–active regions are outlined by red lines (D–F, respectively). 62Cu-ATSM-PET/MR imaging fusion image (D) showing the intratumoral hypoxic region (11.8 cm3), which is less than that of the contrast-enhanced volume (30.9 cm3). FDG-PET/MR imaging fusion image (E) also indicating the intratumoral active region (4.6 cm3), which is heterogeneously distributed compared with the 62Cu-ATSM–active region. MET-PET/MR imaging fusion image (F) showing the more extensive active region (73.1 cm3), which completely covered the 62Cu-ATSM–active regions.
