“This is a great study. It is one of the largest series of prostate-specific membrane antigen (PSMA) scans and covers many patient scenarios, including initial staging, restaging after surgery or radiation or hormonal therapy, and re-imaging in advanced disease,” said Charles G. Drake, MD, PhD, a...
