Recently, a number of Member State have moved towards improvement in generator assembly and novel generator systems partially due to efforts of NAPC. Apart from interest in therapeutic rhenium generator system, there is significant interest in PET radionuclide (Positron emission tomography) producing generator i.e. gallium-68 generator. Positron emission tomography has gained much attention due to favourable imaging characteristics and a generator system could make it more accessible and affordable. This clinical CRP will use these new PET generators and simple routine kit preparation of [68Ga]-tripeptide RGD in oncology under a multicenter study.
