Moreover, in a recent comparative study between 68 Ga-PSMA PET/CT and mpMRI in the diagnosis of lymph node metastases, Franklin A et al. observed that preoperative 68 Ga-PSMA/PET CT was more sensitive in identifying histological pelvic LNM than 3-T mpMRI. This evidence concerns the gene FOLH1 and metastatic malignant neoplasm in the lymph nodes.
