Key result
Pulsed Doppler ultrasound detects carotid stenosis or occlusion with 85% accuracy versus arteriography.
Why the study?
Does pulsed Doppler ultrasonic imaging accurately detect carotid artery stenosis compared to selective contrast arteriograms?
Cross-Sectional (n=118)
Does pulsed Doppler ultrasonic imaging accurately detect carotid artery stenosis compared to selective contrast arteriograms?
Effect estimate: 89% sensitivity, 84% specificity, 85% overall accuracy
Pulsed Doppler ultrasonic imaging demonstrates high sensitivity (89%) and specificity (84%) for detecting significant extracranial carotid artery stenosis compared to contrast arteriography.

May support noninvasive carotid screening; leaves open prospective validation versus modern standards before practice change.
Berry et al. (1980) conducted a cross-sectional in Carotid artery stenosis (n=118). Pulsed Doppler ultrasonic imaging vs. Selective contrast arteriograms was evaluated on Diagnostic accuracy, sensitivity, and specificity for detecting carotid artery stenosis or occlusion (89% sensitivity, 84% specificity, 85% overall accuracy). Pulsed Doppler ultrasonic imaging of the extracranial carotid arteries achieved an overall accuracy of 85%, with 89% sensitivity for detecting >50% stenosis or occlusion compared to arteriography.
