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.
