Multifarious Ga-68 Labeled PET Radiopharmaceuticals in Imaging Various Malignancies.

The gamut of gallium labeled radiopharmaceuticals contributes to augmented variety in molecular imaging approach for in vivo identification of tumor characteristics. The spectrum ranges from somatostatin receptor based target-specific imaging agents, to those used for tumor imaging based on specific receptor types extending into ones used for therapeutic monitoring. The versatility of gallium chemistry provides the needed advantage for imaging which is further exploited in clinical practice influences the specificity of tumor imaging. Ga-68 has revealed applicability in labeling compounds from nanoparticles to micro as well as macromolecules. We in this image, present variety of frequently and infrequently used gallium labeled radiopharmaceuticals, for imaging diverse malignancies other than conventional established tracers.
