Median and ulnar nerve fascicle imaging using MR microscopy and high-resolution ultrasound.

Background And Purpose: Understanding nerve microanatomy is important as different neuropathies and some nerve neoplasms present with fascicle enlargement. The aim of our study was to gain clinically oriented knowledge on nerve fascicular anatomy using imaging modalities.

Methods: On a cadaveric upper extremity, high-resolution ultrasound (HRUS) scan with 22 MHz probe was performed.

Ultrasound-guided injections in pelvic entrapment neuropathies.

Pelvic entrapment neuropathies represent a group of chronic pain syndromes that significantly impede the quality of life. Peripheral nerve entrapment occurs at specific anatomic locations. There are several causes of pelvic entrapment neuropathies, such as intrinsic nerve abnormality or inflammation with scarring of surrounding tissues, and surgical interventions in the abdomen, pelvis and the lower limbs.
