Fig. 4From: Radiation dosimetry of 18F-AzaFol: A first in-human use of a folate receptor PET tracerMean nA ± SD (average values and SD evaluated across the 6 patients), for considered source organs. Mono- and bi-exponential fits of experimental data are displayed in addition to the tail according to pure physical decay to infinity for t > 60 min. For sake of visibility, the time base in each source organ graph was restricted to three times the physical half-life of 18FBack to article page
