Abstract
The advent of numerous noninvasive imaging modalities, such as X-ray, computed tomography, single photonemission-computed tomography, positron emission tomography (PET), magnetic resonance imaging (MRI), ultrasound imaging, radio frequency (rf), and optical imaging now allows scientists and clinicians to acquire in vivo images of the anatomy and physiology of animals and humans.1, 2 Each of these in vivo imaging techniques possesses characteristic strengths and weaknesses. For each imaging modality, substantial attention has been devoted to developing contrast agents not only for improving the contrast of the acquired images, but also for molecular imaging targeting specific biomolecules, cell tracking, and gene expression.3, 4, 5, 6
