[The perspectives of ultrasound use in neurological diagnosis]

Ultrasound and Doppler phenomenon constitute the basis of ultrasound diagnostics in neurosciences. They permit to visualize vessel walls and blood flow and allow the quantitative assessment of its velocity and direction. The last years bring the rapid development of these techniques. The introduction of color flow Doppler, power Doppler and Duplex or Triplex ultrasound systems extended the possibilities of ultrasound diagnostics. Thanks to these applications the new non-invasive methods facilitating the assessment of extra- and intracranial vessels and monitoring of blood flow and collateral circulation in many CNS lesions came into being. The authors review the literature concerning this topic.
