Does 5 MHz continuous-wave Doppler with spectral analysis accurately detect carotid bifurcation disease compared to angiography?
Effect estimate: Sensitivity 94.6%, Specificity 90.7%
5 MHz continuous-wave Doppler with spectral analysis provides high sensitivity and specificity for detecting carotid stenosis ≥30%, though it is insensitive for milder disease.
Norrving et al. (2009) conducted an observational in carotid bifurcation disease (n=86). 5 MHz continuous-wave (C-W) Doppler with spectral analysis vs. angiography was evaluated on detection of stenosis greater than or equal to 30% (Sensitivity 94.6%, Specificity 90.7%). Continuous-wave Doppler with spectral analysis detected carotid stenosis ≥30% with 94.6% sensitivity and 90.7% specificity compared to angiography.
