A 48-channel head and neck neurovascular coil for MR vessel wall imaging at 5 T

Ultra-high field magnetic resonance imaging (MRI) has been increasing in use for human brain imaging. However, due to the absence of a head and neck neurovascular coil, joint imaging of intracranial and extracranial arterial vessel wall has not been applied in current ultra-high field MRI. In this study, a 48-channel head and neck receiver neurovascular coil for joint imaging of intracranial and extracranial arterial vessel wall at 5T was developed. Simultaneous high-resolution imaging of intracranial and extracranial arterial walls with an isotropic spatial resolution of 0.5 mm has been achieved, which further expands the application of ultra-high field imaging.
