3.0T磁共振在臂丛神经成像中的应用研究

目的 探讨3.0T磁共振扫描仪3D-STIR序列增强扫描在臂丛神经成像中的可行性,以及临床应用的效果和价值.方法 对26例志愿者及35例臂丛神经病变的患者,采用3.0T磁共振成像(MRI)常规扫描序列、3D-STIR序列平扫及3D-STIR序列增强扫描,观察所得图像,评价显示情况和对比噪声比.结果 3.0T MRI 3D-STIR序列及其增强扫描可清楚明确地显示所有志愿者臂丛神经的构成、走行、连续性、形态及信号,可以清楚地显示外伤或肿瘤累及臂丛神经所致的各种征象.结论 3.0T磁共振扫描仪3D-STIR序列增强扫描对臂丛神经病变的诊断和治疗有非常重要的价值.

Abstract：

Objective To investigate the feasibility of imaging brachial plexus in enhanced scan of 3D-STIR sequence in 3.0T MRI and the practical value of clinical application. Methods Twenty-six healthy volunteers and 35 patients with brachial plexus lesions underwent imaging of the brachial plexus with 3.0T MRI conventional scanning sequence,3D-STIR sequence scanning and 3D-STIR sequence of enhanced scan. The obtained images were observed to evaluate the image quality and signal to noise ratio. Results 3D-STIR sequence and enhanced scan could clearly display the components,course,continuity,shape and signals of the brachial plexus in all the healthy volunteers. The enhanced scan could improve the suppression effects of the background,and therefore could clearly visualize trauma and tumor involving the brachial plexus due to a variety of signs. Conclusion 3.0T MRI enhanced scan of 3D-STIR sequence has potential values in the diagnosis and treatment of brachial plexus diseases.
