Medical imaging: Colourful future for MRI
Richard Bowtell1
Abstract
Following multiple physiological variables or cell types in vivo requires specific probes. Microfabricated magnetic particles could produce such tuneable contrast agents for magnetic resonance imaging.
Optical imaging routinely uses multicoloured contrast agents ranging from traditional chemical dyes and fluorophores to specially engineered quantum dots. In magnetic resonance imaging (MRI), contrast agents have also proved extremely useful, but their effects are largely indistinguishable from one another, leading to essentially monochrome contrast based on increased or decreased signal strength.
