Exploring the Potential of High-Field MRI: From Basic Tools to Clinical Applications
Abstract: The power of high-field MR magnets may be harnessed to visualize the human brain in unprecedented structural and metabolic detail. Beyond higher resolution images that elucidate finer anatomical features, high-field MR offers greater spectral resolution for spectroscopic imaging, new and enhanced contrast mechanisms and improved detection of nuclei other than protons that are essential to cell processes. Unfortunately, conventional MR imaging sequences, which work well at 1.5T and 3T, are not designed to handle some of the physical and hardware issues that emerge at 7T. This talk will focus on techniques that exploit the benefits offered by 7T magnets for neuroimaging applications by overcoming the limitations associated with their operation. In particular, the design of innovative RF pulses and pulse sequences that perform robustly in the presence of increased field inhomogeneity, RF power deposition and chemical shift, will be presented. Clinical value of these high-field techniques will be discussed, with a particular focus on their application to imaging epilepsy.
