Many patients with hemispheric neurologic symptoms do not have operative stenoses of the
extracranial carotid arteries. In order to assess the frequency of such atherosclerotic lesions …

A high‐resolution ultrasound B‐mode imaging system combined with a 16‐sequential range‐
gated pulsed Doppler flow measuring device was used for the evaluation of nonstenotic …

BACKGROUND AND PURPOSE: Contrast-enhanced MR angiography and extracranial
color-coded duplex sonography are noninvasive, preoperative imaging modalities for …

Twenty-seven patients undergoing carotid endarterectomy (21 M, 6 F), with a mean age of
62 years, were studied by carotid ultrasound imaging, angiography, and histological …

Ultrasonic imaging of the cervical carotid arteries by ultrasonic arteriography and duplex

The results of ultrasonic duplex scanning combined with spectral analysis are compared
with the results of contrast angiography in patients after endarterectomy in which recurrence …

The merits of high-resolution real-time sonography in detection of plaque and estimation of

Eighty-one patients suspected of having cerebrovascular disease had 157 carotid arterial
systems studied by both duplex ultrasonography and contrast arteriography to better define …

Transcranial color‐coded duplex sonography (TCCS), in contrast to “blind” conventional
transcranial Doppler sonography (TCD), enables a sonographer to outline the intracranial …
