Summary

The axillary region is regularly used for brachial plexus block. The technique may be guided by nerve stimulation, ultrasound or a combination of nerve stimulation and ultrasound. Magnetic resonance imaging (MRI) has been beneficial in presenting anatomy of interest for regional anesthesia and in demonstrating spread of local anesthetic (LA). An axillary MRI-study at our department supported the suggestion of multiple rather than a single injection technique. Using a 0.5 Tesla open MR scanner in that study, the investigators were not able to distinguish terminal nerves from equally sized vessels. Therefore the investigators could not definitely answer whether the LA reached the pertinent nerves. The investigators have recently performed an axillary block study with a 3.0 Tesla scanner. Now the terminal nerves were identified and for each patient the investigators could observe if the LA reached the nerves.

The aim of this study was to demonstrate the anatomy of the brachial plexus in the axillary region at different levels. The investigators present the best pictures of the nerves with and without LA injected. The images are demonstrated in the axial and coronal plane.
