Following neonatal ischaemic brain injury, irregular vessels increase in size owing to luxury perfusion. These may be demonstrated by conventional colour flow Doppler (CFD) imaging at the periphery of the infarcted area. We present a case in which power Doppler imaging (PDI) was performed in addition to CFD in a neonate with unexplained seizures and which proved more sensitive than CFD in demonstrating luxury perfusion. Ultrasound appearances were compared with those seen on cranial CT. PDI can be a useful adjunct to conventional CFD examination of the neonatal brain in cerebral infarction.
新生儿缺血性脑损伤后，由于过度灌注，不规则血管会增大。这些血管可通过梗死区域周边的传统彩色多普勒血流成像（CFD）显示出来。我们报告了1例患有不明原因癫痫的新生儿病例，除CFD外还进行了能量多普勒成像（PDI），结果证明在显示过度灌注方面，PDI比CFD更敏感。将超声表现与头颅CT所见进行了比较。在新生儿脑梗死的传统CFD检查中，PDI可以作为一种有用的辅助检查方法。
