The goal of this observational study is to evaluate whether optimized high-resolution MRI can better visualize very fine nerves in the cervical spine and neck region compared to standard MRI. The main question it aims to answer is: Can high-resolution MRI reliably show small nerves and potentially detect their injuries or diseases that are often invisible on conventional MRI scans? Participants will come once to Balgrist University Hospital for a one-hour visit. They will fill out a questionnaire and have a single 30-minute MRI scan of the cervical spine without contrast.
