A Biodistribution of [¹⁸F]olaparib in selected tissues in U251MG (top) or U87MG (bottom) xenografts bearing-mice, 120 min after i.v. administration of [^TotalF]olaparib (0.04–8.0 μg, [¹⁸F]olaparib: 0.28–13.89 MBq) with various molar activities (1–320 GBq/μmol), (n = 3/group). Full biodistribution data are presented in Additional file 1: Tables S2–S3. B Tumour uptake of [¹⁸F]olaparib at various injected masses (μg) and molar activities (also see Additional file 1: Table S4). Asterisks indicate levels of significance: *P < 0.05; **P < 0.01
