Forty to fifty of all strokes are secondary to atherosclerotic disease of the cervical carotid
arteries [1]. Techniques that image the carotid bifurcation have grown in popularity and are …

Scanning of the extracranial carotid arteries with real-time B-mode ultrasound has become
an increasingly popular noninvasive diagnostic technique in the years since its introduction …

Basically two principles have to be distinguished in ultrasonic imaging of arteries. In velocity
imaging blood flow velocities are visualized with continuous wave or pulsed Doppler …

Noninvasive tests for the detection of carotid occlusive disease have focused primarily on
the indirect assessment of the internal carotid artery by the analysis of arterial pressure and …

Examination of 101 common carotid bifurcations using ultrasonic methods is compared with
the findings of transfemoral bidirectional arteriography. In the common and internal carotid …

Duplex scanning of the carotid arteries combines B‐mode ultrasound and Doppler
ultrasound within a single instrument, thus providing both anatomical imaging of the vessel …

Over three decades ago, Doppler was introduced as the first ultrasonographic method for
evaluation of cerebrovascular disease. Since then, the development of new ultrasound …

Technical advances in the field of ultrasound have resulted in the development of a high
resolution real-time B-mode imaging system that permits direct Doppler analysis of …

Materials and methods A specially designed duplex system combining a high resolution B-
scan with a multigated pulsed Doppler was used for ultrasonic imaging, as well as for the …

BACKGROUND: To develop a method that allows B-mode ultrasonic images of carotid
plaques to be standardised so that measurements of plaque echodensity become …
