Musculoskeletal MRI is widely used to evaluate soft
tissues for space-occupying lesions, infection, atrophy,
or fibrotic scarring. 7T MRI can comprehensively explore
nerve (diffusion imaging) and vessel (non-contrast
enhanced MRA imaging and vessel segmentation) via
homogeneous excitation. Our goal is to compare SNR and
CNR findings of 3T vs. 7T MRI for upper extremity with
specific emphasis on peripheral nerve and vasculature.
Taken together, this is a demonstration of the potential
utility and relevance of UHF 7T MRI in upper extremity
applications such as vascular and nerve imaging.
