gallium Ga 68-P15-041

A radiotracer composed of a bone targeting agent P15-041 linked to the radioisotope gallium Ga 68, with potential imaging activity upon positron emission tomography (PET)/computed tomography (CT). Upon administration, the P15-041 moiety targets, through an as of yet unknown mechanism of action, a certain target expressed by bone and, upon PET/CT, bone metastases can be imaged.
