Based on the time-activity curves, [44Sc]Sc-B28110 accumulation was statistically more enhanced in the LNCaP tumours in comparison to the other assessed tracers regarding all time points; however, the tumorous lesions could be clearly detected with the use of all three probes ([44Sc]Sc-B28110, [68Ga]Ga-B28110, and [44Sc]Sc-PSMA-617). The gene discussed is FOLH1; the disease is neoplasm.
