Contrast-enhanced transcranial color-coded real-time sonography. Results of a phase-two study.

Abstract

These preliminary data indicate that the use of a transpulmonary ultrasound contrast agent (SH U 508 A) may substantially broaden the spectrum and potential diagnostic utility of transcranial ultrasound by allowing detection of supratentorial peripheral central nervous system arteries, deep cerebral veins, and (through the foramen magnum) the entire vertebrobasilar system, including the cerebellar arteries.
