Researchers from Case Western Reserve University School of Medicine have developed a new molecular marker known as MeDAS that is used with PET imaging to detect myelin damage in the spinal cord of multiple sclerosis patients.

The approach may allow for noninvasive early detection and monitoring of MS progression, according to the study, which was published in the Annals of Neurology.
