Interventional molecular imaging.

Recent common interest in molecular imaging among both diagnostic and interventional radiologists has led to the establishment of a concept that could be called interventional molecular imaging. This concept, by combining interventional radiology with molecular imaging, is aiming to fully apply the advantages of both imaging fields. Interventional radiology can extend the capabilities of currently available molecular imaging techniques to (a) reach deep-seated targets, (b) enable a close look at small targets, (c) precisely guide delivery of nontargeted imaging tracers or therapeutic agents, and (d) superselectively enhance the effectiveness of targeted imaging and treatment. Interventional molecular imaging is becoming one of the frameworks for bringing molecular imaging from benches and small-animal laboratories to large-animal suites and, ultimately, to certain clinical applications in humans.
