Table 1 SUV values and tumor-to-organ ratios (liver, blood and muscle) for different PCa tumor cell lines with varying PSMA expression levels: PC-3 (no PSMA expression), 22Rv1 (low PSMA expression) and C4-2 (high PSMA expression).

  1. P values were calculated using the Wilcoxon signed-rank test with Holm correction with C4-2 as a reference, the significance level was set at p = 0.05, **p < 0.01, ****p < 0.0001.
  2. aExpression levels were determined by semi-quantitative western blot analysis and are expressed β-actin normalized density.
  3. bActivity in blood was determined by delineation of the heart.
