Imaging the peripheral nerves and their roots can be difficult on MT MRI due to lack of contrast with the surrounding tissues and breathing movements. A new MT DWIBS sequence has been successfully introduced to measure the MTR values for brachial plexus and used for MT, NOE study. Both the nerves and cord showed z-spectra asymmetry. NOE effects could give new insights into the interactions between semisolid tissue and bulk water inside the nerves and cord. In future NOE will be quantified by exploring the z-spectra asymmetry with several offset frequencies and RF powers to study myelination.
