fMRI at UHF:

Current and future challenges

Functional magnetic resonance imaging (fMRI) has become the prime method for non-invasive mapping of activity in the human brain. It is based on blood oxygenation changes due to neuronal activity arising from the differences in susceptibility between oxygenated and deoxygenated blood. With higher magnetic field strengths, not only signal strength and sensitivity for detecting neuronal activity increase but also the impact of artefacts from field inhomogeneities and physiological fluctuations. This is particularly the case for ultra-high field fMRI at 7 Tesla.

Using some of our recent 7T fMRI studies, I will show ways to overcome these challenges successfully by optimising imaging sequences and improving post-processing procedures, in order to push the limits of fMRI applications. Examples ranging from population receptive field retinotopic mapping with sub-millimeter resolution and high-resolution functional mapping in the basal ganglia to amygdala sub-nuclei assessment and high-resolution language mapping, will demonstrate the versatility of 7T fMRI across a range of basic science and clinical applications.
