ExamCard description

This ExamCard is created on a release 5.1.7 Ingenia 1.5T system for visualization of nerves, particularly in the brachial plexus.

The dS HeadNeckSpine coil solution is used. The dS Base, dS Head, dS Posterior and dS Anterior coil are used for scanning.

ExamCard overview

 <br>

The total scan time is 7:27 min.

The 3D STIR sequences in this ExamCard are optimized for fat suppression in the brachial plexus region for visualization of the nerves. Good results are obtained in this challenging region with a large FOV.

A large coverage is obtained with 300 slices, a large FOV of 250 x 250 mm and 
isotropic voxels of 1.24 x 1.24 x 1.24 mm. 

The 3D VIEW technique is used to get an effective TE of 85 ms.
dS SENSE is used to reduce scan time (P-reduction 2, S-reduction 2).

Patient preparation

The patient is positioned head first and supine.
The Anterior coil is positioned adjacent to the dS Head coil to obtain high SNR and image quality in the lower neck region.
No contrast agent needed for these scans.

Postprocessing / analysis

The ExamCard includes three postprocessing steps with the VolumeView package to obtain images in different directions and to create coronal slab MIPs.
