Baohong Yuan and Joshua Rychak have written an interesting review in the February 2013 American Journal of Pathology that outlines emerging techniques based on ultrasound to obtain functional and molecular imaging of tumors. Apart from being fascinating reading, this article underscores how the disciplines of radiology and pathology may merge at certain points sometime in the future. Abstract:
Tumor functional and molecular imaging has significantly contributed to cancer preclinical research and clinical applications. Among typical imaging modalities, ultrasonic and optical techniques are two commonly used methods; both share several common features such as cost efficiency, absence of ionizing radiation, relatively inexpensive contrast agents, and comparable maximum-imaging depth. Ultrasonic and optical techniques are also complementary in imaging resolution, molecular sensitivity, and imaging space (vascular and extravascular). The marriage between ultrasonic and optical techniques takes advantages of both techniques. This review introduces tumor functional and molecular imaging using microbubble-based ultrasound and ultrasound-mediated optical imaging techniques.
