摘　　要：目的探讨使用单倍剂量对比剂结合3D_STIR_SPACE序列在臂丛神经成像应用价值。方法对20例临床怀疑臂丛神经损伤的患者,进行一次注射单倍剂量(0.1mmol/kg)对比剂,行臂丛神经3D STIR SPACE磁共振检查,所有患者均为注射造影剂后1min进行扫描,获得图像后进一步行后处理重建,采用最大密度投影像(MIP)。图像分为3个等级,同时观察神经的病变情况。结果所有患者均能完成检查,20例臂丛神经成像显示清晰,达到Ⅰ级或Ⅱ级图像,无Ⅲ级图像。结论使用单倍剂量(0.1mmol/kg)对比剂一次性注射后,采用3T磁共振3D STIR SPACE序列进行增强扫描,所得臂丛神经影像可以满足临床诊断需求。Objective To investigate the clinical application value of haploid dose of contrast agent using MRI 3D-STIR SPACE sequence of brachial plexus imaging. Methods 20 patients with suspected brachial plexus injury were injected with single close （tendency for 0.1mmol/kg） contrast agent,the line of brachial plexus 3D-STIR SPACE is checked,all are finished medicine immediately scan in a minute, get the image after the use of maximum density projection （MIP） as further post-processing recon- struction. The image is divided into three levels, and at the same time observe the nerve lesion. Results All patients can complete inspection,20 cases of brachial plexus imaging showed clear,level Ⅰ or Ⅱ images,no level Ⅲ image. Conclusion MR 3D-STIR SPACE sequence with single dose （tendency for 0.1mmol/kg） one-time injection line of contrast agent can clearly show the branchial plexus ,which meet the demands of clinical diagnosis.
