We investigated the diagnostic potential of transcranial color-coded real-time sonography in 52 individuals using a phased-array ultrasound system with color-coded blood flow representation. Ultrasound scans in the axial and coronal planes were feasible through temporal acoustic bone windows in 49 subjects, enabling depiction of the main parenchymal and vascular structures as well as the ventricular system. Color-coded representation of blood flow in the cerebral vessels allowed unequivocal identification of the circle of Willis within the anatomic black-and-white B-mode image of the parenchymal structures. In Doppler mode, vascular blood flow phenomena may be analyzed semiquantitatively using the Doppler frequency spectrum. This noninvasive, serially applicable, mobile beside method may complement conventional neuroradiologic imaging methods, allowing on-line studies of functional processes within the adult brain.
我们使用带有彩色编码血流显示的相控阵超声系统,对52名个体进行经颅彩色编码实时超声检查的诊断潜力进行了研究。在49名受试者中,通过颞骨声窗在轴向和冠状平面进行超声扫描是可行的,能够描绘主要的实质和血管结构以及脑室系统。脑血管中血流的彩色编码显示能够在实质结构的解剖黑白B模式图像中明确识别 Willis 环。在多普勒模式下,可以使用多普勒频谱对血管血流现象进行半定量分析。这种非侵入性、可连续应用、床边可移动的方法可以补充传统的神经放射成像方法,允许对成人大脑内的功能过程进行在线研究。
