We investigated the contribution of colour Doppler flow imaging (CDFI) to duplex-ultrasonography of the neonatal brain. In pre- and full-term infants, CDFI facilitated spectral analysis of blood flow velocity wave forms in most major intracranial arteries, enabling blood flow velocity measurements. Moreover CDFI depicted major deep and superficial veins, enabling venous blood flow velocity measurements. Smaller arteries could also be imaged in a substantial number of infants in regions with haemorrhagic or ischaemic lesions. The method may also offer the opportunity to assess regional cerebral blood flow in the neonatal brain, although further study is necessary to determine whether accurate, reproducible flow velocity measurements are possible in these vessels.
我们研究了彩色多普勒血流成像（CDFI）对新生儿脑双功超声检查的作用。在早产儿和足月儿中，CDFI有助于对大多数主要颅内动脉的血流速度波形进行频谱分析，从而能够测量血流速度。此外，CDFI还能显示主要的深静脉和浅静脉，从而能够测量静脉血流速度。在有出血或缺血性病变的区域，相当数量的婴儿中较小的动脉也能成像。该方法还可能提供评估新生儿脑局部脑血流的机会，不过还需要进一步研究以确定在这些血管中是否能够进行准确、可重复的血流速度测量。
