低出生体重(LBW)儿脑室内出血和脑室周围白质软化与神经疾病关系密切。超声影像对脑室内出血及脑室周围白质软化有较高的特异性和敏感性。将1990年1月～1995年6月出生体重在500～1750g的745例新生儿分为胎膜早破组(PROM,279例),胎膜完整的早产组(PTC,285例)和因母亲或胎儿因素而终断妊娠的医源性早产组(MD-IND,181例)。生后3天和7天进行标准的矢状和冠状扫描。异常扫描包括各级脑室内出血、脑室内出血伴脑室周围白质软化和脑室周围白质软化。主要损伤包括3、4级脑室内出血、脑室内出血伴脑室周围白质
Low birth weight (LBW) in children with intraventricular hemorrhage and periventricular leukomalacia and nerve disease are closely related. Ultrasound imaging of intraventricular hemorrhage and periventricular white matter softening has a higher specificity and sensitivity. From January 1990 to June 1995, 745 newborns with birth weight of 500 ~ 1750g were divided into premature rupture of membranes (PROM, 279 cases), premature rupture of membranes (PTC, 285 cases) and mothers Or fetal factors and termination of pregnancy iatrogenic preterm group (MD-IND, 181 cases). Standard sagittal and coronal scans were performed 3 and 7 days after birth. Abnormalities include intraventricular hemorrhage at all levels, intraventricular hemorrhage with periventricular leukomalacia and periventricular leukomalacia. The main injury, including grade 3,4 intraventricular hemorrhage, intraventricular hemorrhage with ventricular white matter
