Abstract
Abstract:
Magnetic resonance imaging is most commonly employed, alongside electrodiagnostic
studies, in the diagnosis of ulnar nerve entrapment. It is expensive, time consuming,
not readily available to the general public, and limits imaging to a segment of the nerve at any
given time. In contrast, high-frequency ultrasound is an inexpensive imaging modality with
a flexible field of view through which the nerve can be traced. An ultrasound cross-sectional
area (CSA) >0.075 cm² has previously been suggested as indicative of nerve entrapment.
