A Gallium-68 (Ga-68) generator is a device used in nuclear medicine to provide a source of Ga-68, a radioisotope used in positron emission tomography (PET) imaging. Gallium-68 is important in diagnostic imaging, particularly for oncology, cardiology, and neurology, due to its favorable half-life (about 68 minutes) and its ability to form complexes with various radiopharmaceuticals.
