Fig. 5From: Synthesis and preclinical evaluation of novel 99mTc-labeled PSMA ligands for radioguided surgery of prostate cancerTumor-to-background ratios (TBR) of 99mTc-labeled N4-PSMA compounds and [99mTc]Tc-PSMA-I&S at 6 h p.i. in male LNCaP tumor-bearing CB17-SCID mice. Data are given as mean ± standard deviation (n = 4–5). Mean values were determined from TBR calculated for individual animals. gl.: gland; submand.: submandibularBack to article page
