[Possible target specific molecular imaging with ultrasound contrast agents]

Non-invasive molecular imaging technologies provide researchers with the opportunity to study cellular and molecular processes. Among different imaging technologies, ultrasound based molecular imaging methods are also of interest, since the use of ultrasound contrast agents allows specific and sensitive depiction of molecular targets. Recent studies are encouraging and have demonstrated the feasibility of ultrasound based molecular imaging. This review summarizes current experiences and recent preclinical studies with target-specific ultrasound contrast agents.
