There has recently been an increased interest in
diagnosing abnormalities of the brachial plexus with
MRI. STIR is often used in assessing the brachial plexus
since chemical saturation techniques may be insufficient
for homogenous fat suppression. On STIR images, however,
some vessels including the internal jugular veins,
paraspinal vessels, and others around the brachial
plexus are hyperintense compared to the fat and
surrounding tissues. Recently, blood-suppression pulse
technique has been introduced to reduce signal
intensities from vessels and microperfusion of the
tissues at 3T MRI.The MIP image of 3D SPACE STIR
technique with blood-suppression pulse is superior to
that without. It might be a better way to evaluate
anatomies and pathologies of the brachial plexus.
