摘要目的 探讨3D快速自旋回波-短时反转恢复序列(3D SPACE-STIR)增强成像在臂丛节后神经成像中的应用价值.方法 43例可疑臂丛神经病变患者,同时接受了3D SPACE-STIR平扫及增强检查,对比臂丛节后神经的信噪比(SNR)、对比噪声比(CNR)以及根、干、股、束的显示效果.对比3D SPACE-STIR平扫和增强的SNR和CNR,采用配对样本t检验;对比3D SPACE-STIR平扫和增强对根、干、股、束的显示情况,采用非参数配对Wilcoxon符号秩检验.结果 与3D SPACE-STIR平扫相比,增强扫描的神经SNR差异没有统计学意义(左侧分别为37.41±7.34、36.27±7.66,t=1.574,P=0.123;右侧分别为43.85±9.56、42.34±9.74,t=1.937,P=0.073),但神经-肌肉CNR(左侧分别为24.01 ±6.31、26.39±6.95,右侧分别为29.31 ±7.84、31.77±8.85,t值分别为-3.278、-3.278,P值均<0.01)和神经-淋巴结CNR显著提高(左侧分别为-0.84±10.51、15.35±8.02,右侧分别为-8.47±10.85、19.30±10.35,t值分别为-15.984、-15.651,P值均<0.01),差异有统计学意义.3D SPACE-STIR增强显示根和干明显优于平扫(Z值分别为-3.606、-4.472,P值均<0.001),但显示股和束的能力与平扫类似(Z值分别为-1.732、-1.414,P值均>0.05).在3D SPACE-STIR增强中,肿瘤性病变倾向于信号明显下降,其显示效果差于平扫.结论 3D SPACE-STIR增强对臂丛神经和非肿瘤性病变的显示有明显优势,但对肿瘤性病变则可能存在不足. Objective To evaluate the contrast-enhanced 3D sampling perfection with application-optimized contrasts by using different flip angle evolutions-short TI inversion recovery sequence (SPACE-STIR) for the imaging of the post-ganglionic segments of the brachial plexus.Methods Forty-three patients with suspected brachial plexus lesions were examined with 3D SPACE-STIR and contrast-enhanced 3D SPACE-STIR prospectively.Signal-to-noise ratios (SNR),contrast-to-noise ratios (CNR),and the conspicuousness of roots,trunks,divisions and cords of the brachial plexus of the two 3D sequences were retrospectively compared.Statistical analysis was performed by using student t-test and Wilcoxon rank sum test.Results Compared with 3D SPACE-STIR,contrast-enhanced 3D SPACE-STIR provided the similar SNRs (left,37.41 ±7.34 vs 36.27 ±7.66,t =1.574,P =0.123,right,43.85 ±9.56 vs 42.34 ±9.74,t =1.937,P =0.073),but significantly higher nerve-to-muscle CNRs (left,24.01 ± 6.31 vs 26.39 ± 6.95,right,29.31 ± 7.84 vs 31.77 ± 8.85,t =-3.278,-3.278,both P < 0.01) and nerve-to-lymph gland CNRs(left,-0.84 ± 10.51 vs 15.35 ±8.02,right,-8.47 ± 10.85 vs 19.30 ± 10.35,t =-15.984,-15.651,both P <0.01).The conspicuousness of roots and trunks on contrast-enhanced 3D SPACE-STIR was significantly better than that on 3D SPACE-STIR (Z =-3.606,-4.472,P < 0.01),while the conspicuousness of divisions and cords was similar(Z =-1.732,-1.414,P =0.083,0.157).The signal intensity of neoplastic lesions on contrast-enhanced 3D SPACE-STIR tended to decrease rapidly,thus the lesion conspicuousness was worse than that on 3D SPACE-STIR.Conclusions Contrast-enhanced 3D SPACE-STIR has obvious advantages in displaying normal brachial plexus and revealing non-neoplastic lesions of the brachial plexus,but may be insufficient for the diagnosis of neoplastic lesions of the brachial plexus.
