Detect Disease Earlier With Mmri

Magnetic resonance medical imaging, which is built on the principles of nuclear magnetic resonance, creates an image of the NMR signal in a thin slice through the human body. Images taken in sequence build a three dimensional image of anatomical structures. Magnetic resonance medical imaging is the diagnostic tool of choice for visualizing the nervous system and assessing soft tissue.

Molecular magnetic resonance medical imaging allows for the visualization and analysis of cells and molecules. At this level, it's possible to stalk and assess cellular functions that can provide never-before-available insight into the nature of the disease process. For example, there has long been an established connection between inflammation and heart disease. However, the medical imaging tools to calculate inflammation related to the heart have simply not been accessible at a fine enough level of measurement to completely explore the relationship.

On January sixteenth 2007 the Proceedings of the National Academy of Sciences published a study that uses molecular MRI medical imaging to obtain insight into the relationship between inflammation and heart disease. Researchers developed a synthetic material, gadolinium�diethyltriaminepentaacetic acid (DTPA), that's able to discover and connect to white blood cells imbedded in arterial walls. The DPTA permitted mMRI medical imaging visualization of the WBC's, providing the ability to actually count the number of cells and assess how stable they are. Researchers found a positive connection between the amount of white cells imbedded in the arterial walls and the probability of later heart attack. The primary research was conducted on mice.

Further research will soon be conducted on bigger mammals and if it's successful, the research will move to human clinical trials. The discovery of better, more effective and more specific medical imaging "tagging" media is the hottest new area of research in molecular magnetic resonance medical imaging. Recently, 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 regular MRI techniques. The method, named 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 particular protein target. This method will most likely be very useful in detecting cancer cells at the very earliest stages of cancer presence.
