Table 2 Linear regression results: Pearson correlation coefficient r and the obtained regression parameters are shown

From: Dual time point based quantification of metabolic uptake rates in 18F-FDG PET

  r Slope (mean ± SD) Intercept (mean ± SD)
K m vs. K s 0.98 0.98 ± 0.05 -0.54 ± 0.13
K m vs. K s ( c ) 0.99 0.98 ± 0.04 0.04 ± 0.10
K m vs. c t + 0.60 1.62 ± 0.48 2.81 ± 1.33
K m vs. RI 0.88 11.38 ± 1.34 5.44 ± 3.79
  1. All correlations were found to be statistically significant with p < 0.005. Chosen units are in milliliters per minute per 100 ml for K m , K s , and K s ( c ) ; SUV for c t + ; and percentage for RI (from which the respective slope and intercept units follow).
