Quantitative and qualitative analysis of biodistribution and PET image quality of novel radiohybrid PSMA ligand, 18F- rhPSMA-7, in patients with prostate cancer

Conclusions: Quantitative analysis shows uptake of 18F-rhPSMA-7 in tumour lesions is stable across multiple uptake times and administered activities. As low tracer retention in the bladder and bone marrow are important features for PSMA ligand imaging, and the highest overall image quality was achieved with short uptake times, the use of low activities (222-296 MBq) and an early imaging timepoint (50-70min) is recommended for 18F-rhPSMA-7.
