Gastrin-releasing Peptide Receptor Imaging in Breast Cancer Using the Receptor Antagonist ⁶⁸Ga-RM2 And PET

Abstract

Our study demonstrates that (68)Ga-RM2-PET/CT is a promising imaging method in ER-positive breast cancer. In vivo GRPR binding assessed by (68)Ga-RM2-PET/CT correlated with ER expression in primary tumors of untreated patients.
