34例外伤性臂丛神经损伤患者的手术探查和术中体感诱发电位结果与脊髓造影和磁共振成像（MRI）结果相关，以确定MRI是否可以识别神经根撕脱伤。冠状面和矢状面不能显示单个神经根的撕脱。轴位和轴位斜平面确实提供了有用的信息，以确定哪个神经根在上丛撕脱，虽然很难清楚地描绘下颈神经根。MRI对C5和C6的准确性分别为73%和64%，脊髓造影对C5和C6的准确性分别为63%和64%。因此，MRI对上神经根的诊断准确性略优于脊髓造影上级。虽然其主要诊断价值仅限于上神经根，其撕脱相对难以通过脊髓造影诊断，但MRI可以在臂丛损伤后手术探查前的等待期提供有用的指导。
Findings in 34 patients with traumatic brachial plexus injury documented by surgical exploration and intra-operative somatosensory-evoked potentials were correlated with findings on myelography and magnetic resonance imaging (MRI) to determine whether MRI can identify nerve root avulsion. The coronal and sagittal planes were not able to demonstrate avulsion of the individual nerve roots. The axial and axial oblique planes did provide useful information to determine which nerve root was avulsed in the upper plexus, although it was difficult to clearly delineate the lower cervical rootlets. The accuracy of MRI was 73% for C5 and 64% for C6 and that of myelography 63% for C5 and 64% for C6. Thus, the diagnostic accuracy of MRI for upper nerve roots was slightly superior to myelography. Although its primary diagnostic value is limited to the upper nerve roots whose avulsion is relatively difficult to diagnose by myelography, MRI can provide useful guidance in the waiting period prior to surgical exploration after brachial plexus injury.
