Since the typical length scale of water diffusion in tissue during an MRI experiment is around 1 µm, DTI can reveal structural information well below the nominal image resolution using biophysical modeling of the signal. In this Webinar, Dr. Philipp Boehm-Sturm will review the basics of diffusion imaging, as well as introduce the use of DTI connectomics for characterization of animal models of disease.
Dr. Boehm-Sturm will review protocol adaptation as well as good practice. He will then introduce sets of methods to reconstruct fiber tracts from DTI data and subsequent network analysis, the so-called DTI connectomics. Finally, from this information, structural and physiological parameters of the brain such as axone degradation, loss of tissue integrity or demyelinization can be elucidated. This particular approach will be demonstrated to characterize a mouse model of vascular cognitive impairment.
Any scientist, research assistant or other academics with routine MRI knowledge who want to know more about diffusion imaging, as well as people who wish to get more out of their MRI system.
