摘要
新生儿缺氧缺血性脑病(HIE)是新生儿期发病率较高又可导致死亡或致残的严重疾病。由于磁共振成像有极好的对比分辨率,并且无创、无X线辐射的危害,因此是HIE最适合的影像学检查方法。近年来随着磁共振成像技术的飞速发展,特别是磁共振成像的功能成像如扩散加权成像、灌注成像、扩散张量成像、磁共振波谱成像等新技术的出现为更加深入地研究HIE的病理基础提供了可能,为早期准确诊断及评估预后提供了一种可靠的手段和方法。现将磁共振成像新技术对新生儿HIE的临床应用价值及研究进展予以综述。
Hypoxic-ischemic encephalopathy(HIE) is a kind of severe disease resulting in death and mutilation with high incidence during neonate period. Because MRI has excellent contrast resolution with non-invasive and without X-ray radiation hazard. Therefore MR/is the most appropriate imaging examination and diagnosis. With the rapid development of MRI technology, especially the new techniques,such as diffusion-weighted imaging, perfusion imaging, diffusion tensor imaging, magnetic resonance spectroscopy and so on, have provide the possibility to study the pathological basis of HIE, which provide a reliable method to diagnose this disease and evaluate its prognosis earlier and accurately. This article reviews MR/about its clinical application and progresses in HIE of neonate.
