Advancing molecular imaging: a chairman's perspective on how radiology can meet the challenge

Abstract

To date, most molecular imaging techniques applied clinically have offered relatively general information about the metabolism and physiology of diseased cells and tissues. However, due to recent scientific and technological advances, much more specifically targeted molecular imaging probes (e.g., reporter gene probes, whole cell-tracking probes, and probes for localizing specific biomolecules) are now being used in preclinical research and, in some cases, translated to the clinical setting. As a result, the imaging community is poised to help lead a revolution in personalized, molecularly targeted medicine. This article considers the importance of molecular imaging for advancing research and clinical care both within individual institutions and across the medical field. It outlines specific steps that leaders in academic radiology can take to hasten progress in molecular imaging and explains why they must have the courage to reach across traditional interdisciplinary boundaries and advocate for major investments in equipment, education, and personnel.
