Brachial plexus MRI Protocol

·        Coronal T2 FSE (large FOV)

·        Axial T1 SE (large FOV)

·        Axial T1 SE

·        Axial STIR

·        Coronal (Oblique) T1 SE

·        Coronal (Oblique) STIR

Post contrast brachial plexus MRI Protocol

·        Opt: post-Gd axial T1 SE with fat saturation

·        Opt: post-Gd coronal (Oblique) T1 SE with fat saturation

·        Opt: post-Gd sagittal (Oblique) T1 SE with fat saturation

Optional T1 Fat Sat CORONAL & SAGITTAL sequences preffered. 

Field of view

The field of view (FOV) is 17-22 cm for the direct coronal orientation and 14-17 cm for 
sagittal or oblique sagittal orientations.

Section thickness

The recommended section thickness is 3 mm with an intersection gap of 0-0.5 mm for 
direct coronal imaging and 4 mm with an intersection gap of 1-2 mm for sagittal or 
oblique sagittal imaging. If axial images are obtained, 4-mm thickness with a 1- to 1.5-
mm intersection gap may be performed.

Technical notes for "Brachial plexus MRI Protocol"

The axial images are obtained perpendicular to the long axis of cervical
vertebrae in the coronal plane
The oblique sagittal images are perpendicular to the long axis of the plexus 
demonstrating the cross-section of the plexus more accurately than true sagittal
 imaging
The axial images are obtained perpendicular to the long axis of cervical
vertebrae in the coronal plane.
The roots of the Brachial plexus can be identified by Axial images but the other 
 components bettr seen by Coronal & Sagital images.
