Sonomorphologische Charakterisierung arteriosklerotischer Plaques - Möglichkeiten und Grenzen der hochauflösenden B-Scan-Sonographie

: One hundred and five carotid stenoses were examined by B-scan sonography (10 MHz) and the results compared with the macroscopic and histological appearances. The most important sonographic findings depended on surface structure, echo amplitude and the presence of acoustic shadows. From the therapeutic point of view, B-scan sonography is complementary to angiography by evaluating the morphology of the plaques, particularly if the indications for surgery are ill-defined.
