Professor Andrew G. Webb, Director of the C. J. Gorter Center for High-Field MRI, Leiden University Medical Center, will be visiting Center for Hyperpolarization in Magnetic Resonance at DTU on 16 September 2015.

Professor Webb will give a presentation on Alzheimer’s disease, eye tumors, high permittivity materials and plasmas: 7 Tesla MRI applications and technology.



With the rapid spread of 7 tesla whole body MRI systems throughout the world there has been significant recent progress in both clinical and clinical research applications. Although predominantly in the neurological area, there have also been many developments in the areas of musculoskeletal, cardiac and ocular imaging. Increased magnetic susceptibility contrast, enhanced magnetic resonance angiography, and much higher signal-to-noise in spectroscopy and hetero-nuclear imaging/spectroscopy have been the driving forces for much of this progress. The major challenges have been, and continue to be, increased image inhomogeneity, power deposition, and motion-induced artifacts. Many hardware advances have already been necessary to deal with these problems, and many future advances are required to keep the field moving forward.


Examples which will be presented include: (i) the use of navigator echoes and phase imaging for high resolution MRI in Alzheimer’s patients, (ii) the use of high dielectric materials to improve neuroimaging and spectroscopy at high field, and (iii) the design of new types of RF coil specifically for high field, including dielectric resonators and plasma mediated magnetic resonance.



Everyone is welcome. The lecture is given at DTU Electrical Engineering, Building 348, room 129 and starts 15:30.


The mission of the Gorter Center at LUMC is to develop new MRI techniques for high field clinical applications, both in humans and in animal models. Find more information on Professor Webb and the Gorter Center at the LUMC website.
