In the context of fast expansion of 7T clinical MR systems for neurological applications, a retrospective evaluation of cervical spinal cord image quality acquired on 41 patients and 25 healthy controls was performed. Several morphometric parameters were collected, and four MR modalities were rated. Altogether, this study provides guidance for both clinicians and physicists, regarding current sequence robustness and most frequent problems to be addressed.
