Key result
Computerized ultrasonic arteriography detects carotid narrowing with 100% sensitivity compared to vessel X-rays.
Why the study?
Does computerized ultrasonic arteriography accurately detect carotid occlusive disease compared to vessel X-rays?
Observational (n=94)
Does computerized ultrasonic arteriography accurately detect carotid occlusive disease compared to vessel X-rays?
Effect estimate: Sensitivity 100%, Specificity 85%

May support noninvasive carotid screening; leaves open prospective validation before replacing angiography.
Miles et al. (1982) conducted an observational in Carotid occlusive disease (n=94). Computerized ultrasonic arteriography vs. Vessel X-rays was evaluated on Detection of 40 percent diameter reductions (Sensitivity 100%, Specificity 85%). Computerized ultrasonic arteriography detected 40% diameter reductions in the carotid bifurcation with 100% sensitivity and 85% specificity compared to vessel X-rays.
