Application of MRI neuroimaging technology in cervical plexus and brachial plexus of normal adults

Objective: To explore the MRI findings of Diffusion-weighted images with the background signal suppression(DWIBSS) and MRI myelography(MRM)of cervical plexus and brachial plexus in normal adults,and its application value.Methods: The MRI findings of DWIBSS and MRM of the cervical plexus and brachial plexus in 102 healthy adults were analyzed.Results: In addition to C4,the neural stems of C5 to T1 could almost be displayed,and tracked to the axillary nerve in the MRI findings of DWIBSS.The imaging of MRM could display the entire spinal cord,nerve root sleeve and walking nerve root within nerve root sleeve.Conclusions: The findings of DWIBSS combined with MRM have high spatial and tissue resolution,and can provide more detailedly anatomical information of the cervical plexus and brachial plexus,which has a broad application prospect.
