  • Note:—Min indicates minute; Rot, rotation time.
  • ↵a All 3D PET data were reconstructed using VUE Point FX (GE Healthcare) TOF and Sharp IR; 64Cu-DOTATATE: 256 matrix, 3 iterations, 8 subsets, “standard” z-axis filter, and a Gaussian postfilter of 7.0-mm FWHM; 68Ga DOTATATE: 192 matrix, 2 iterations, 24 subsets, standard z-axis filter, and a Gaussian postfilter of 6.4-mm FWHM.
  • ↵b All helical CT configurations used 120 kV(peak), 3.75-mm section thickness, and a 0.8-second rotation.
