Task-Evoked Metabolic Balance and Intrinsic Network Organization Relate to Processing Speed

Abstract Processing speed is a core component of cognition that declines with aging and is impaired across neurological and psychiatric disorders. We combined functional proton magnetic resonance spectroscopy at 7 T with resting-state functional MRI to examine neurochemical and f...

T2 mapping of individual fascicles of the sciatic nerve at 7 T using multi-echo spin–echo

Abstract Objective Neuropathies can selectively affect individual fascicles within peripheral nerves, but diagnosis is limited by MRI spatial resolution and signal-to-noise ratio. This feasibility study aimed to leverage 7 T MRI to measure sub-millimetric T 2 maps of sciatic nerv...
