BACKGROUND
To investigate the use of three-dimensional (3D) brain magnetic resonance imaging (MRI) to evaluate in preterm children with periventricular leukomalacia.
MATERIALS AND METHODS
Semiautomated 3D classification of the gray and white tissues was used to reconstruct brain images of patients with confirmed periventricular leukomalacia from 2D MRI.
RESULTS
We studied 14 preterm patients. The gestational age ranged from 25-37 weeks. The corrected age ranged from 5-49 months. We reconstructed the gray matter, white matter, and ventricles in order to analyze the brain volume.
CONCLUSION
Three-dimensional MRI is a good tool that can be used to demonstrate brain lesions in stereo and differentiate the gray matter, white matter, and ventricles. Brain volume can also be accurately evaluated.
背景
研究使用三维（3D）脑磁共振成像（MRI）来评估患有脑室周围白质软化症的早产儿。
材料与方法
使用半自动的 3D 分类方法对 2D MRI 确认的脑室周围白质软化症患者的灰质和白质组织进行重建。
结果
我们研究了 14 名早产儿患者。胎龄范围为 25-37 周。校正年龄范围为 5-49 个月。我们重建了灰质、白质和脑室，以分析脑容量。
结论
三维 MRI 是一种很好的工具，可以用于立体显示脑损伤，区分灰质、白质和脑室。还可以准确评估脑容量。
