Vessel wall MRI(vwMRI) increases diagnostic accuracy for stroke etiologies without overt luminal irregularities, such as mild atherosclerosis, subtle dissection, or vasculitis. Prior vwMRI research has focused on the head or neck in isolation. We developed a set of two neck-shape-specific(NSS) coil that fit two different neck sizes and configured them to integrate with the existing commercial head coils. The purpose of this work was to develop a 3D vwMRI protocol, leveraging the NSS coil array, which permits simultaneous imaging of the head and neck vessels in a single scan. By allowing an efficient examination and identifying patients at high risk of future recurrent stroke, this technique will enable detection of cryptogenic stroke sources and optimal personalized management of vascular disease.
