| Abstract | |
| 177Lu-PSMA-617 was prepared at the optimized conditions (95°C, 15-18 µg peptide, 35-40 min; solid phase purification) using 177Lu obtained from 176Lu(n, γ)177Lu reaction(>98%, ITLC, HPLC, S.A. 22-24 TBq/mM) followed by stability (up to 48 h), biodistribution studies (up to 168 h), planar imaging, compartmental modeling and dosimetry estimations via Sparks’s extrapolation method in human organs. Kidney is the critical organ with the dose of 0.067 mGy/MBq and the radiopharmaceutical can be safely used in trials considering the human dose. | |
