MR neurography in right elbow

Case Study
Wang, Guangbin, M.D., Ph.D. Shandong Medical Imaging Reseach Institute • China, People's Republic of

Patient history

A 26-year-old healthy male volunteer underwent MRI neurography (MRN) at Shandong Medical Imaging Research Institute, China, to visualize peripheral nerves in the right elbow.

MR examination

The MR neurography based on DWIBS was performed on a Release 5.1.7 Achieva 3.0T TX with a SENSE Flex L coil.

The axial DW source image shows the median (M), ulnar (U), and radial (R) nerves.

On postprocessed full-volume MIP images in anteroposterior and left lateral projections nerves, articular fluids (F) and vessels (V) show hyperintensity. However, nerves can be easily separated from articular fluids and vessels by rotating in different projections.

The postprocessed DW image with MIP reconstruction and volume editing in anteroposterior projection demonstrates the median (M), ulnar (U), and radial (R) nerves. Articular fluids and vessels were removed from this image during postprocessing. Axial T2-weighted SPAIR obtained at same level also shows the median (M), ulnar (U), and radial (R) nerves, but not clearly as MR neurography

Diagnosis

Using MR neurography using DWIBS allows clear visualization of the nerves of the elbow in this healthy volunteer. No abnormalities are seen.

Clinical impact of MR neurography

In this case study MR neurography based on DWIBS clearly visualizes the peripheral nerves in the elbow. It is more difficult to see the nerves in the axial SPAIR image than in the axial DWI image.
