Webnormal tracer distribution is paramount. The aim of this study was to describe the normal distribution pattern of 18F-Choline by measuring the maximum standardized uptake values (SUVs) of various organs. Methods: 18F-Choline PET was performed in ten consecutive patients. Approximately 370 MBq of tracer was injected WebIn a preliminary dosimetry study, in two patients [68 Ga]Ga-FAPI-04 demonstrated a rapid tumor uptake, fast clearance via the kidneys, and very low tracer uptake in normal organs . However, in the same study, considerable tracer clearance from the tumors was reported, with tumor uptake dropping from 1 to 3 h post-injection (pi) by 25%.
