There is a large amount of fat in the postganglionic segment of the brachial plexus nerve. The use of short T1 inversion recovery pulse sequence may improve signal strength of the brachial plexus postganglionic segment. The present study revealed that the combination of three-dimensional fast imaging employing steady-state acquisition with phase-cycled and short T1 inversion recovery pulse sequence clearly displayed the anatomical morphology and structure of the brachial plexus nerve, together with maximum intensity projection, volume rendering and other three-dimensional reconstruction techniques. Our results suggested that this method is also suitable for providing accurate assessment and diagnosis of the site, severity and scope of brachial plexus injury.
