The purpose of this study entitled, “Molecular Phenotyping and Image-Guided Surgical Treatment of Prostate Cancer Using Ultrasmall Silica Nanoparticles”, is to determine the usefulness of [64Cu]-NOTA-PSMA-PEG-Cy5.5-C′ tracer as a safe and reliable tool in identifying tumour cells before and during surgery and to find whether PET/MRI scans conducted after injection of this NP-based tracer are more accurate than the usual imaging scans used to locate deposits of prostate tumour cells. Here, FOLH1 is linked to prostate carcinoma.
