Full-term infants with early-stage brain injuries from asphyxia were examined with two-dimensional ultrasound and color Doppler to assess the use of ultrasound in evaluating early brain injuries after neonatal asphyxia. The sonographic features of ultrasound and color Doppler were compared to those of magnetic resonance imaging (MRI). Ultrasound was used to monitor the brain parenchyma, lateral ventricles, and cerebral hemodynamics in the asphyxia group and full-term control group 24, 48, and 72 h after birth. MRI and diffusion-weight imaging (DWI) were performed within 72 h. Cerebral edema changes were most obvious with ultrasound within 48 h of asphyxia, while the cerebral hemodynamic changes were most obvious within 24 h. These results suggested that ultrasound detected early cerebral edema better than MRI did.
对足月窒息早期脑损伤婴儿进行二维超声和彩色多普勒检查，以评估超声在新生儿窒息后早期脑损伤评估中的应用。将超声和彩色多普勒的超声特征与磁共振成像（MRI）的特征进行比较。在出生后24、48和72小时，对窒息组和足月对照组的脑实质、侧脑室和脑血流动力学进行超声监测。在72小时内进行MRI和弥散加权成像（DWI）检查。窒息后48小时内超声显示脑水肿变化最明显，而脑血流动力学变化在24小时内最明显。这些结果表明，超声在检测早期脑水肿方面优于MRI。
