In a series of experiments, MGH researchers systematically increased the gradient strength of the Connectom scanner from 90mT/m to 300 mT/m using DSI and noted increasing ability to resolve finer and finer white matter fiber structure in the living human.  These results are the first to be obtained using ultra-high gradient strength, illustrate the advantages on connectivity of using stronger gradients, and will form the basis of additional data collection to explore fiber bundle density and examine more subtle connections between diverse parts of the brain.  These results are to be reported at the ISMRM annual conference in Melbourne, Australia, May 5-11, 2012.
