Disorders of the peripheral nervous system have traditionally been evaluated using clinical history, physical examination, and electro- diagnostic testing. In selected cases, imaging modalities such as magnetic resonance (MR) neurography may help further localize
or characterize abnormalities associated with peripheral neuropa- thies, and the clinical importance of such techniques is increasing. However, MR image interpretation with respect to peripheral nerve anatomy and disease often presents a diagnostic challenge because the relevant knowledge base remains relatively specialized. Using the radiology knowledge resource RadLex®, a series of RadLex queries, the Annotation and Image Markup standard for image annotation, and a Web services–based software architecture, the au- thors developed an application that allows ontology-assisted image navigation.The application provides an image browsing interface, allowing users to visually inspect the imaging appearance of ana- tomic structures. By interacting directly with the images, users can access additional structure-related information that is derived from RadLex (eg, muscle innervation, muscle attachment sites).These data also serve as conceptual links to navigate from one portion of the imaging atlas to another.With 3.0-T MR neurography of the brachial plexus as the initial area of interest, the resulting applica- tion provides support to radiologists in the image interpretation process by allowing efficient exploration of the MR imaging appear- ance of relevant nerve segments, muscles, bone structures, vascular landmarks, anatomic spaces, and entrapment sites, and the investi- gation of neuromuscular relationships.
