Injected activity per renal absorbed dose at the first cycle vs. the product of body surface area and estimated glomerular filtration rate (n = 77). There was a moderate correlation between variables (Spearman r = 0.39, P = 0.0005). The slope of the linear regression curve forced through origin (solid line; 95% confidence interval, dashed lines), which was 0.012 GBq · min × 1.73/mL/Gy, is to be used to adjust the injected activity at the first cycle in a personalized PRRT protocol
