Three‐dimensional (3D) ultrasonography reconstructing from power flow Doppler imaging (PF) is able to image the 3D structures of the vascular systems. We tried to display the 3D images of intracranial vascular structures in 5 neonates with a portable data processor. Data acquisition was performed using PF through the anterior fontanel. We succeeded in reconstructing vivid 3D images of the anterior cerebral arteries (ACA), basilar artery (BA), internal carotid arteries (ICA), middle cerebral arteries (MCA), lenticulostriate arteries (LSA), internal cerebral vein (ICV), the vein of Galen (GV) and straight sinus (SS) in all subjects. The MCA could be displayed in only a proximal portion. The images of the LSAs were fainter than the other vessels. These problems are based on the character of PF; the flow signal, sampling from the small sized vessels and the perpendicular vessels to ultrasonic beam, is weak. The images of these vessels are fainter than other vessels. These limitations of PF performance directly influence the quality of the 3D images. The benefits and limitations of 3D ultrasonography system are discussed.
