Summary
Innovative imaging techniques are enhancing our understanding of the cervical spinal cord. This study evaluated four radiofrequency coil designs for 7 T MRI, aiming to improve image quality. By establishing a quality control protocol, researchers found significant performance variations, paving the way for better diagnostic tools in spinal health.
Abstract
Purpose The depth within the body, small diameter, long length, and varying tissue surrounding the spinal cord impose specific considerations when designing radiofrequency coils. The optimal coil configuration for 7 T cervical spinal cord MRI is unknown and, currently, there are very few coil options. The purpose of this work was (1) to establish a quality control protocol for evaluating 7 T cervical spinal cord coils and (2) to use that protocol to evaluate the performance of 4 different coil designs.
