Synopsis

Keywords: RF Arrays & Systems, High-Field MRI, carotid array

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 fields

Approach: 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.
