Development and Preclinical Evaluation of [68Ga]Ga-DOTA-L3: A Novel PET Tracer for Quantitative Imaging of Carbonic Anhydrase IX
Carbonic anhydrase IX (CA IX) is a key biomarker for tumor hypoxia and a promising target for molecular imaging. In this study, we developed [68Ga]Ga-DOTA-L3, a novel small-molecule CA IX-targeted PET tracer. The radiolabeling was optimized to consistently achieve a radiochemical purity of >98% (10 μg precursor, 90 °...
