Neurografía por resonancia magnética: Aspectos técnicos y aplicaciones clínicas

Abstract

The evaluation of the peripheral nerve in magnetic resonance imaging (MRI) can be challenging, further- more, a significant number of injuries can be unseen when using classic protocols. In recent years, the availability of selective nerve sequences has increased. Each of these sequences has specific technical requirements and artifacts that must be known to avoid diagnostic errors. The purpose of this article is to review the advances in magnetic resonance neurography (NRM) protocol by applying isotropic, functional techniques -such as diffusion (DWI) and images with diffusion tensor (DTI)-, fat suppression and blood flow, with emphasis in acquisition protocols, technical difficulties and clinical applications.
