The nuclei of the basal ganglia pose a special problem for functional MRI, especially at ultra-high field, because T2* variations between different regions result in suboptimal BOLD sensitivity when using gradient-echo echo-planar imaging (EPI). Specifically, the iron-rich lentiform nucleus of the basal ganglia, including the putamen and globus pallidus, suffers from substantial signal loss when imaging...
PurposeHead motion is a significant problem in diffusion‐weighted imaging as it may cause signal attenuation due to residual dephasing during strong diffusion encoding gradients even in single‐shot acquisitions. Here, we present a new real‐time method to prevent motion‐induced signal loss in DWI of the brain.
MethodsThe method requires a fast motion tracking system (optical in the current implementation)...
