摘要 目的对比观察31-40孕周胎儿标本与宫内活体胎儿脑磁共振(MRI)图像,探讨两种图像对胎儿脑沟的显示程度。方法选取20例(每孕周2例)31~40孕周胎儿标本,行3.0TMRI常规序列扫描。选取20例(每孕周2例)3l^40周宫内正常胎儿,行脑1.5TMRI半傅立叶单激励快速自旋回波(HASTE)序列扫描。对相同孕龄的标本与宫内胎儿图像在对应的横、矢、冠方位上进行对比,观察不同孕期脑沟在富内与标本MRI上的发育及显示状况。结果标本与宫内胎儿图像在显示脑沟的发育上有较好的一致性,脑裂、主要脑沟均可明确显示,且前者在显示信息的清晰性、丰富性与准确性上优于宫内胎儿图像。结论31-40孕周宫内活体胎儿脑1.5TMRI图像与标本胎儿3.0TMRI图像有良好的一致性,能理想显示胎儿脑沟的发育变化,标本胎儿3.0TMRI图像对J]~JL脑发育的研究可提供精确的影像依据。
