【摘要】：目的:探讨3.0T磁共振断层血管成像(MRTA)各种扫描方法在脑神经血管压迫综合征中的应用,并分析各种方法的优缺点。方法:对50例临床诊断为面肌痉挛的患者,进行t1-vibe-fs、t2-space-p2、3D-TOF FLASH三种序列扫描后,计算各组图像信号噪声比(SNR)和对比噪声比(CNR),并分析比较其图像质量。结果 :t1-vibe-fs、t2-space-p2两种序列图像的SNR与CNR均高于3D-TOF FLASH序列(P均0.05),t1-vibe-fs序列图像的SNR高于t2-space-p2序列(P0.05),CNR低于t2-space-p2序列(P0.05)。t1-vibe-fs、t2-space-p2两种序列的图像质量评分均高于3D-TOF FLASH序列(P均0.05),t2-space-p2序列的图像质量评分高于t1-vibe-fs序列(P0.05)。结论:MRTA技术能清楚显示颅神经及责任血管,t1-vibe-fs结合t2-space-p2对颅神经血管压迫综合征有重要价值。
[Abstract]:Objective: to investigate the application of 3.0T MRTA-MRTA in neurovascular compression syndrome and analyze the advantages and disadvantages of these methods. Methods: 50 patients with hemifacial spasm were scanned by t1-vibe-fst2-space-p2p2D-TOF FLASH. The image signal noise ratio (SNR) and contrast noise ratio (CRR) were calculated, and the image quality was analyzed and compared. Results the SNR and CNR of the two kinds of images were higher than those of 3D-TOF FLASH sequences (P = 0.05) and t2-space-p2 sequences (P < 0.05). T1-vibe-fsst2-space-p2 images had higher image quality scores than those of 3D-TOF FLASH sequences (P < 0.05) and t2-space-p2 sequences (P < 0.05). T1-vibe-fsst2-space-p2 sequences had higher image quality scores than those of 3D-TOF FLASH sequences (P < 0.05). The score was higher than that of t1-vibe-fs sequence (P 0.05). Conclusion it is valuable to display cranial nerves and responsible vessels of cranial nerves and responsible vessels with t2-space-p2 combined with t2-space-p2 in the diagnosis of cranial nerve and vascular compression syndrome.
