Abstract

MR neurography (MRN) has evolved to become a clinically useful imaging modality for evaluating nerve pathologies. Anatomically, nerves are often surrounded by fat and blood vessels, which appear bright on MR images impeding the conspicuity of nerve visualization. Additionally, nerves are tortuous and would be preferable to visualize in three dimensions for proper diagnosis. Various technical advancements in the field of MR imaging in general have led to volumetric acquisitions with uniform fat and blood suppression. These advancements enabled optimized imaging protocols for better visualization of the nerves. This review article discusses some of these technical advancements that enabled current MRN protocols in routine clinical imaging and certain research techniques that may facilitate nerve disorder characterization following interventions.
