The ability of duplex scanning to characterise the component tissue of atheromatous lesions of the internal carotid artery and to detect ulceration has been examined in a histological study of 42 carotid endarterectomy specimens. The results suggest that the only component of atheromatous lesions of the internal carotid artery which can be characterised from the B-scan is calcification. The presence of ulceration, intraluminal and intramural thrombus, fibrous intimal thickening and necrosis are not related to the echogenic appearance of internal carotid stenoses and may not be detected reliably. B-mode imaging alone cannot reliably grade greater than 50% internal carotid stenoses, but when this is combined with pulsed Doppler in the technique of duplex scanning, accurate results may be obtained.
在一项对42个颈动脉内膜切除术标本的组织学研究中，已对双功扫描鉴别颈内动脉粥样硬化病变的组成组织及检测溃疡形成的能力进行了检查。结果表明，颈内动脉粥样硬化病变中唯一可从B超扫描中鉴别的组成部分是钙化。溃疡形成、管腔内和壁内血栓、纤维内膜增厚及坏死的存在与颈内动脉狭窄的回声表现无关，可能无法可靠检测到。仅B模式成像无法可靠地对大于50%的颈内动脉狭窄进行分级，但在双功扫描技术中将其与脉冲多普勒相结合时，可获得准确结果。
