Researchers have developed a new magnetic resonance imaging (MRI) technique that detects the telltale signs of multiple sclerosis in finer detail than ever before.
The technique analyzes the frequency of electro-magnetic waves collected by an MRI scanner, instead of the size of those waves. Although analyzing the number of waves per second had long been considered a more sensitive way of detecting changes in tissue structure, the math needed to create usable images had proved daunting. Researchers found frequency changes at areas on scans – indicating tissue damage – at least two months before any sign of damage appeared at those sites on conventional scans.
