【摘要】目的 探讨MR 3D -STIR SPACE序列增强扫描在臂丛节后神经成像的可行性及应用价值.方法 对20例志愿者和10例臂丛神经病变患者行T2WI-STIR、平扫和增强3D -STIR SPACE序列扫描.评价3种方法 对臂丛节后神经的显示情况、对比噪声比(contrast noise ratio,CNR)及图像伪影,观察臂丛神经及其病变在3D -STIR SPACE序列增强扫描中的MR表现.结果 T2WI-STIR、平扫和增强3D -STIR SPACE序列扫描臂丛神经锁骨上段显示率分别为80%、80%、85%,臂丛锁骨下段显示率分别为55%、60%、85%.3种序列CNR分别为34.05±11.48、34.10±11.30、44.59±11.26,3D -STIR SPACE序列增强扫描对臂丛节后神经的CNR及其锁骨下段的显示率高于其他2种方法,增强扫描能明显改善背景抑制效果,减少伪影,病变显示更清晰.结论 3D-STIR SPACE序列增强扫描能更清楚地显示臂丛神经及其病变,有助于臂丛神经病变的诊断及治疗.%Objective To discuss the feasibility and values of enhanced MRI using 3D-STIR SPACE sequence in displaying the post-ganglionic nerve of the brachial plexus. Methods 20 volunteers and 10 patients suffering from brachial plexus diseases underwent MRI using T2WI-STIR, unenhanced and enhanced 3D-STIR SPACE sequences, respectively. The displaying rate of the post-ganglionic nerve, contrast noise ratio(CNR)
and artifacts of images at the three sequences were evaluated. The signs of the normal brachial plexus and its lesions at contrast-enhanced MRI using 3D-STIR SPACE sequence were observed. Results The displaying rates of supra-clavicular and subclavicular segment of the brachial plexus on T2WI-STIR, un-enhanced and enhanced 3D-STIR SPACE images were 80%, 80%, 85% and 55% ,60% ,85% , respectively. The CNR of three sequences above were 34. 05 ±11. 48, 34. 10 ± 11. 30 and 44. 59 ±11. 26, respectively. The CNR of the post-ganglionic nerve of the brachial plexus and the displaying rate of subclavicular segment of the brachial plexus with enhanced 3D-STIR SPACE were higher than that with other two sequences. Enhanced scan could significantly improve the background suppression effect, reduce the artifacts, and show the brachial plexus and its lesions more clearly. Conclusion The enhanced 3D-STIR SPACE sequence can clearly display the brachial plexus and its lesions, contribute a lot of informations to the diagnosis and treatment for brachial plexus lesions. 【总页数】5页(1763-1767)
