A Novel 8-channel Carotid Array with Two Wireless Resonators Insert for Magnetic Resonance Imaging at 5T

Abstract

Motivation: Ultra-high field MRI is popular in brain imaging research. However, high-res imaging of carotid vessels and walls is not possible due to the lack of a carotid array. Goal(s): High-resolution imaging of the neck position at ultra-high fieldsApproach: In this study, carotid array with two wireless resonators insert was developed at 5T. Results: SNR was significantly improved using the novel coil in comparison with the only carotid array at 5T. Impact: An 8-channel carotid array with wireless resonators was designed for 5T magnetic resonance imaging. Water model imaging provides sufficient signal-to-noise ratio and resolution for high-field imaging, meeting the requirements for detailed neck artery disease feature descriptions.
