An extremely important medical imaging development in detecting diseases is magnetic resonance imaging. This is dependent on the injection of contrast material to highlight specific tissue or to distinguish between healthy and diseased tissue. The materials used in this procedure tend to have the drawback of being either simply constructed and stable in the body but providing low contrast OR more complex in construction and providing sharper contrast but with less stability. The National Institute of Standards and Technology has been collaborating with researchers at Florida State University and the University of Colorado at Boulder to produce new medical imaging contrast materials that are highly magnetic, highly uniform (and thereby easier to manage) and tiny. This blend of attributes will work together to make a harmless, predictable, highly effective contract solution to be used in medical imaging. Naresh Dalal (a Florida State University researcher) and additional researchers have developed a magnetic molecule identified as Fe8. Fe8 includes every one of the desirable traits. This molecule magnet has eight ion bonds, is water-soluble and non-toxic. Recently published articles describe the molecules test results which show that Fe8 provides good contrast in non-clinical MRI studies over a specific range of concentrations, dispelling a former confusion regarding the value of Fe8 in medical imaging. The research had resulted in conflicting results because the concentration of Fe8 hadn't been accounted for during testing. These developments are partly due to advances in the field of nanotechnology. Nanotechnologists work with elements that are one billionth of a meter thick. The techniques that measure and manipulate such small particles will support additional research on materials such as Fe8. Researchers are counting on this new contrast media to be able to be manipulated for even better benefit than this preliminary research implies. For instance, researchers are looking for ways to turn on and turn off the contrast traits by synthesizing contrast media that attaches only to specific other molecules or binds only when subject to certain conditions that can be monitored and supervised. Regardless of the fact that this breakthrough in contrast media for medical imaging is extremely promising and may provide a large leap forward in the quality of magnetic resonance imaging, there's still a immense amount of testing and research that must take place before Fe8 can be made available for use in human population studies.
