Clusters of inflammatory cells in the leptomeningeal compartment are suspected to contribute directly to subpial cortical demyelination and neurodegeneration in patients with multiple sclerosis (MS). Clinical post-contrast 3D T2-FLAIR detects these clusters through the leakage of a T1 contrast agent into inflammatory foci and the subarachnoid space, referred to as leptomeningeal contrast enhancement (LMCE). While leptomeningeal inflammation has been reported in rodent models of MS, LMCE has not been used to study disease pathology in the preclinical setting.

In this work, we present an imaging protocol for LMCE imaging in the experimental autoimmune encephalomyelitis myelin oligodendrocyte glycoprotein (EAE-MOG) murine model of MS at 9.4 Tesla.
