Possibilities of spatial imaging of carotid arteries pathologies in Power-Doppler US

The aim of the study was to assess the value of Power-Doppler US spatial reconstructions in examining pathologies of carotid arteries for determining its role in the diagnostic algorithm. 3D Power-Doppler US reconstructions were performed in 19 patients with pathologies of carotid arteries qualified for surgical treatment on the basis of Color-Doppler examinations. Digital data of 2D US sections secondarily gave spatial pictures. Most frequently, 14 times, different degrees of carotid artery stenosis were found, in 3 cases critical, and complete impatency was observed twice. The narrowings were caused by both atheromas and parietal clots. In 3 cases the internal carotid artery formed an angular refraction. Spatial pictures also determined the geometry of division of common carotid arteries. It was found that Power-Doppler 3D US perspectively visualizes the configuration of carotid vessels and the range of their pathology facilitating understanding of the extent of changes and mutual topographic relationships. Spatial imaging let visualize atheromas and ulcerations of their surfaces besides the degree of carotid arteries narrowing.
