中文摘要:
      目的 与背景抑制DWI(DWIBS)、基于3D短T1反转恢复(3D-STIR)序列对比,探讨3D-nerve序列对新生儿臂丛神经的成像效果。方法 对15例臂丛神经损伤的新生儿行MR扫描,扫描序列包括3D-nerve、DWBIS、3D-STIR,评估每个序列图像的血管搏动伪影、脂肪抑制均匀性及臂丛神经分支的显示效果,并测量神经-脂肪比,神经-肌肉比。结果 臂丛神经在DWIBS序列图像上显示效果差,无法观察;3D-nerve血管搏动伪影和脂肪抑制不均匀与3D-STIR比较差异均无统计学意义(P均>0.05)。3D-nerve、3D-STIR对新生儿臂丛神经根、神经干的显示率均为100%(15/15);3D nerve对神经束、神经支的显示率为100%(15/15)和66.67%(10/15),3D-STIR对神经束、神经支的显示率为93.33%(14/15)和53.33%(8/15),差异无统计学意义(P=1.00、0.71)。3D-nerve序列神经-脂肪比和神经-肌肉比优于3D-STIR序列,差异有统计学意义(P均<0.05)。结论 3D-nerve序列在新生儿臂丛神经损伤中的成像效果明显优于DWBIS及3D-STIR序列。
英文摘要:
      Objective To analyze the imaging effect of 3D-nerve on brachial plexus in neonates compared with DWI with background body singal suppression (DWIBS), 3D-short T1 inversion recovery (3D-STIR). Methods A total of 15 neonates with brachial plexus injury were recruited and underwent MR scan with sequences including 3D-nerve, DWBIS, 3D-STIR. Images were evaluated for pulsation artifact, heterogeneous fat saturation, brachial plexus branches, nerve-fat ratio, nerve-muscle ratio. Results The brachial plexus showed poor results in DWIBS sequence images, which could not be observed. Pulsation artifact and heterogeneous fat saturation had no statistical significance between 3D-nerve and 3D-STIR (both P>0.05). 3D-nerve and 3D-STIR showed 100% (15/15) of the brachial plexus roots and brachial plexus trunks. Brachial plexus bundles, brachial plexus branches were seen in 100% (15/15), 66.67% (10/15) on 3D nerve and 93.33% (14/15), 53.33% (8/15) on 3D-STIR, the differences were not statistically significant (P=1.00, 0.71). 3D-nerve performed better nerve-to-fat ratio and neuro-to-muscle ratio compared with 3D-STIR (both P<0.05). Conclusion The 3D-nerve performed better for neonatal brachial plexus injury than DWBIS and 3D-STIR.
