【摘要】：目的:比较3.0T MRI FIESTA与IDEAL序列腰骶神经根受压成像的诊断价值。方法:22例腰椎间盘突出患者分别行常规序列、FIESTA序列和IDEAL序列扫描,所有图像均进行后处理重建,对图像的质量和清晰度、受压神经显示清晰度、腰骶神经根与邻近椎体(脑脊液)的对比噪声比4个方面进行评价。结果:神经根-脑脊液CNR值FIESTA序列明显大于IDEAL序列(283.24±117.97 vs 96.28±39.29,P=0.000),图像质量及清晰度评分FIESTA序列大于IDEAL序列(4.66±0.33 vs 4.22±0.68,P=0.028),受压神经显示清晰度IDEAL序列大于FIESTA序列(2.78±0.45 vs 2.19±0.83,P=0.023),差异均有统计学意义。结论:FIESTA序列扫描时间短,观察神经根受压及治疗前后比较,较有优势;IDEAL序列对于受压神经根的定位、神经根受压及损伤程度的成像特点更有优势。
[Abstract]:Objective: to compare the diagnostic value of lumbosacral nerve root compression imaging between 3.0T MRI FIESTA and IDEAL sequence. Methods: 22 patients with lumbar disc herniation were scanned with conventional sequence, FIESTA sequence and IDEAL sequence respectively. All the images were post-processed and reconstructed. The quality and clarity of the images and the clarity of the compressed nerve were observed. The contrast noise ratio between lumbosacral nerve root and adjacent vertebral body (cerebrospinal fluid) was evaluated in four aspects. Results: the CNR value of nerve root and cerebrospinal fluid in FIESTA sequence was significantly higher than that in IDEAL sequence (283.24 卤117.97 vs 96.2839.29, P < 0.000). The image quality and clarity score of FIESTA sequence was higher than that of IDEAL sequence (4.66 卤0.33 vs 4.22 卤0.68, P < 0.028). The IDEAL sequence of compressed nerve showed greater clarity than that of FIESTA sequence (2.78 卤0.45 vs 2.19 卤0.83, P < 0.023), and the difference was statistically significant. Conclusion: the scanning time of FIESTA sequence is short, it has advantage to observe nerve root compression and compare before and after treatment, and IDEAL sequence has advantage in localization of compressed nerve root, compression of nerve root and degree of injury.
