Table 9 Lesion-based comparison of the values at T2 and T1

From: [68Ga]Ga-PSMA-11 PET before and after initial long-term androgen deprivation in patients with newly diagnosed prostate cancer: a retrospective single-center study

  Value in T2 ≤ T1

  1. All differences are significant with a p < 0.01
  2. LN: liver normalization [value divided by hepatic SUVmean]
  3. aTwo bone metastases newly occurred at T2, and thus, higher values are seen at T2 in all surrogate parameters
