3.0T MR 3D-FIESTA序列成像对诊断血管压迫性三叉神经痛的应用价值

The application value of 3.0T MR 3D-FIESTA sequence imaging in the diagnosis of trigeminal neuralgia

探讨3.0T MR 3D-FIESTA序列成像技术对诊断血管压迫性三叉神经痛(TN)的应用价值。应用3.0T MR 3D-FIESTA序列成像技术对本院30例血管压迫性TN患者进行影像学分析及诊断,观察每例患者的诊断结果。结果显示患者经3.0T MR 3D-FIESTA序列成像技术诊断结果与患者后期的微血管减压术(MVD)术中结果相吻合,TN的一侧图像可显示出血管受到压迫,而未出现三叉神经痛的一侧其图像显示出血管未受到压迫,3.0T MR3D-FIESTA序列成像技术可较为明显地将患者血管的压迫情况及临床症状统一地展示出来。说明3.0T MR 3DFIESTA序列成像技术可有效辨别血管压迫性TN患者的责任动、静脉与神经的毗邻关系,可显著提高血管压迫性TN诊断的敏感度与准确率,为MVD治疗TN提供更准确的解剖学信息,具有较大的临床应用价值。

To investigate the value of 3.0T MR 3D-FIESTA sequence imaging technique in the diagnosis of vascular compression trigeminal neuralgia （TN）. 3.0T MR 3D-FIESTA sequence imaging technique was used to perform imaging analysis and diagnosis on 30 patients with vascular compression TN in our hospital. The diagnostic results of each patient were observed. The results showed that the patient s 3.0T MR 3D-FIESTA sequenced imaging technique was consistent with the patient s later microvascular decompression （MVD） results. One side of TN images showed vascular compression without trigeminal nerves. On the side of the pain, the images showed that the blood vessels were not oppressed, and the 3.0 T MR 3D-FIESTA sequence imaging technique could clearly show the pressure and clinical symptoms of the patient s blood vessels. This study demonstrated that the 3.0T MR 3D-FIESTA sequencer imaging technique can effectively identify the adjacent relationship between responsible arteries and veins and nerves in patients with vascular compression TN, and can significantly improve the sensitivity and accuracy of vascular compression TN diagnosis. TN provides more accurate anatomical information and has greater clinical application value.
