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。
