Key result
Multimodality noninvasive imaging classified more patients as having >50% carotid stenosis compared to arteriography by a ratio of 2:1, and correlated best with operative findings.

Do multimodality noninvasive imaging techniques reliably diagnose carotid bifurcation disease compared to arteriography?
Multimodality noninvasive imaging is a reliable, risk-free alternative to arteriography for diagnosing carotid bifurcation disease and correlates well with operative findings.

May support noninvasive carotid imaging over arteriography; leaves open prospective validation before practice change.
An analysis of 212 carotid arteries studied by Doppler imaging, B-mode imaging, and spectral analysis reveals poor correlation though similarity of data base by chi-square and gamma is strong. The differences between arteriogra phy and the noninvasive techniques appear mainly in the categories of normal and > 50% stenosis. Arteriography classifies more patients as normal and non invasives classify more patients as > 50% by a ratio of 2:1. Noninvasive studies can be used to verify the findings using multiple techniques without risk and correlate best with operative findings. Evidence indicates that multimodality noninvasive studies are a reliable way of diagnosing carotid bifurcation disease and may be used in place of arteriography.

Lefemine et al. (1990) conducted a cross-sectional in Carotid bifurcation disease (n=212). Multimodality noninvasive imaging (Doppler, B-mode, spectral analysis) vs. Arteriography was evaluated on Diagnosis of >50% carotid stenosis. Multimodality noninvasive imaging classified more patients as having >50% carotid stenosis compared to arteriography by a ratio of 2:1, and correlated best with operative findings.
