RT Journal Article SR Electronic T1 MR of spinal meningeal melanocytoma. JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

The lesion showed increased signal intensity on T1-weighted MR images relative to gray matter, was isointense with gray matter on T2-weighted images, and enhanced mildly but homogeneously after administration of contrast material.
