PRESENT STATUS OF TRANSCRANIAL COLOR-CODE D SONOGRAPHY IN ADULTS

Technical improvements accomplished over the last few years allow imag ing of intracranial parenchymal structures as well as of basal cerebra l arteries by ultrasound. Low frequency probes (2-2.5 MHz) and colour Doppler technology are required for these examinations. Recent experie nce in clinical practice proves that perfusion patterns in basal cereb ral arteries can be depicted more accurately and with better reproduci bility compared to conventional transcranial Doppler sonography. Simul taneous B-Mode imaging allows detection of cerebral haemorrhage, brain tumours and ventricular enlargement. Preliminary data on the sensitiv ity and specificity are promising and encourage further prospective st udies.
