Magnetic resonance medical imaging, built on the principles of nuclear magnetic resonance, generates a picture of the NMR signal in a narrow slice right through the human body. Photographs taken consecutively create a 3D picture of anatomical structures. Magnetic resonance medical imaging is the preferred analytical tool for viewing the brain and spinal cord and assessing soft tissue. Molecular magnetic resonance medical imaging allows for the visualization and analysis of cells and molecules. At this level, it's feasible to stalk and evaluate cellular functions that can give never-before-available medical imaging insight into the disease process. For instance, there has long been an established correlation between inflammation and heart disease. Yet, the medical imaging tools to calculate inflammation related to the heart have simply not been accessible at a adequate enough level of measurement to entirely explore the correlation. On January sixteenth 2007 the Proceedings of the National Academy of Sciences printed a study that uses molecular MRI medical imaging to get insight into the relationship connecting inflammation and heart disease. Researchers built a synthetic material, gadoliniumdiethyltriaminepentaacetic acid (DTPA), that has the ability to find and attach to WBC's (white blood cells) imbedded in arterial walls. The DPTA allowed mMRI medical imaging visualization of the white blood cells, they could actually count the number of cells and assess how stable they are. Researchers discovered a correlation between the number of white cells stuck in the arterial walls and the likelihood of subsequent heart attack. The original research was done on mice. Additional research will be conducted on larger animals and if successful, human clinical trails will follow. The discovery of more effective and more exact medical imaging tagging media is the hottest new field of research in molecular magnetic resonance medical imaging. Lately, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have given their report on research concerning a modern medical imaging method for molecular magnetic resonance imaging (MRI) that can perceive molecules ten thousand times lower concentrations than conventional MRI techniques. The method, called HYPER-CEST, for hyperpolarized xenon chemical exchange saturation transfer, hyperpolarizes atoms with laser light to enhance their MRI signal, then puts the atoms into a nanoscale cage biosensor that is made specifically for a individual protein target. This medical imaging method is expected to be very useful in detecting cancer cells at the very earliest stages of cancer.
