摘　　要：目的探讨颈椎线圈联合体部阵列线圈使用SPACE-STIR序列对臂丛神经显示的应用价值。方法选择30例颈椎MRI检查的患者，其中男性18例．女性12例；年龄25-54岁，平均年龄33岁；无臂丛神经病史和相关临床症状。5例外伤后临床怀疑臂丛神经受累的患者．其中男性3例．女性2例：年龄17-54岁，中位年龄41岁。使用3．0TMRI对患者行MRI检查。采用横断位快速自旋回波T1WI、T2WI及冠状位SPACE-STIR序列，观察各序列中臂丛神经图像显示的情况及其病变的MRI影像学特征。检查中对同一被检者仅使用颈椎线圈和使用颈椎线圈联合体部相控阵线圈各检查1次，检验两种方法臂丛神经远端清晰显示率。结果30例颈椎检查者共60侧臂丛神经．使用颈椎线圈T1WI上臂丛神经显示优良率为50％，T2WI为52％，SPACE-STIR为70％；颈椎联合体部阵列线圈T1WI上臂丛神经显示优良率为67％，T2WI为77％，SPACE-STIR为97％。SPACE～STIR序列优于快速自旋回波T1WI、T2WI。使用颈椎线圈联合体部阵列线圈臂丛神经远端清晰显示率为93％，而单独使用颈椎线圈清晰显示率为52％；两者比较，差异具有统计学意义（χ^2=26．12，P〈0．05）。5例臂丛神经损伤诊断结果MRI示神经连续性中断。结论联合线圈成像结果对臂丛神经显示较单个线圈全面、清晰，且对准确判断病变累及范围特别是远端更有优势。联合常规T1WI、T2WI序列更能有效、全面地显示臂丛神经。Objective To observe the value of SPACE-short TI inversion-recovery （SPACE-STIR） sequence in diagnosis of brachial plexus by cervical coil jointed with body coil Methods A total of 30 patients of cervical performed MRI examination were enrolled, included 18 males and 12 females, who were aged 25 - 54 years old with a mean age of 33, and none of them had brachial plexus history or clinical symptoms. Five clinically suspected cases of traumatic brachial plexus were involved, included 3 males and 2 females, who were aged 17 - 54 years old with a mean age of 41. All of them underwent 3.0 T MRI by fast spin echo T1W1, T2WI and SPACE-STIR sequence to observe the MRI features of brachial plexus and pathologic changes in each sequence. The results were processed in Siemens MMWP workstation to test the clear display rate of brachial plexus nerve, every patient was examined twice, one with cervical coil and the other with cervical coil jointed with body coil. Results The 60 side brachial plexus morphology of 30 patients were clearly showed, cervical spine coil by T1WI brachial plexus had excellent and good display rate of 50 %, 52 % for T2WI and 70 % for SPACE-STIR; cervical joint body array coil TiWI brachial plexus had excellent and good display rate of 67 %, T2WI of 77 % and SPACE-STIR of 97 %. The SPACE-STIR sequence was better than that of fast spin echo T1WI and T2WI. The use of cervical spine coil and body coil brachial plexus nerve distal had clear show rate of 93 %, while the individual use of cervical coil had clear show rate of 52 %. The Chi-square test showed the difference was statistically significant（x2 = 26.12, P 〈 0.05）. Five cases of brachial plexus injury diagnosis results in the MRI showed neural discontinuity. Conclusion Joint coils imaging could show the brachial plexus clearer than conventional sequences by cervical coil, and also have advantage in accurately determining the range of lesions involving brachial plexus. Combined with conventional T1WI, T2WI sequence, the SPACE-STIR sequence c
