目的：：探讨正常人颈、臂丛全身背景信号抑制弥散加权( DWIBSS)和MRI脊髓成像( MRM)表现及其应用价值。方法：对102名健康成人颈、臂丛DWIBSS和MRM表现进行分析。结果：在DWIBSS图像中,除C4外,C5~T1神经干几乎均可显示,并追踪到腋神经处。与DWIBSS成像不同, MRM成像能显示整个(也可分段显示)脊髓、各神经根袖和其内走行的神经根。结论：DWIBSS结合MRM等能够获得较高的空间分辨率,较高的组织分辨率和更细节的颈、臂丛解剖信息,具有广阔的应用前景。

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.
