  • * Patient 2 had primary tumor excised before scanning.

  • Input curve was lost because of technical difficulties.

  • SUV = standardized uptake value; PHA = percentage hypoxic area (SUV) of 18F-FDG, and hypoxic fraction (PHA) as percentage of voxels above T/M = 1.5 3 h after injection of 18F-EF5.

  • LN designates lymph node metastasis of preceding patient. Metabolism is expressed as SUV.
