Introduction . Molecular-targeted imaging (MTI) is becoming increasingly important for identifying, diagnosing, and treating cancers. It allows cells, which express a cancer-associated biomarker to be non-invasively detected in real time. Antibodies, which display high affinity and specificity for their targets are often used as MTI probes to detect cancer-associated biomarkers. As a therapeutic, antibodies are desirable because of their long half-lives, which allows for tri-weekly treat...
