High-resolution ultrasonography (US) and magnetic resonance neurography (MRN) have
followed parallel paths for peripheral nerve imaging with little comparison of the
two modalities. They seem equally effective to study a variety of neuropathies affecting
large and small nerves in the wrist and hand. This article outlines the technical
considerations of US and MRN and discusses normal and abnormal imaging appearances
of hand and wrist nerves from etiologies such as entrapment, injury, tumor, and proximal
and diffuse neuropathy, with specific case illustrations.
