Anecdotal reports have described a false-positive" jet effect" or velocity increase in the
carotid artery contralateral to an artery with significant stenosis or occlusion when using …

To determine if a significant contralateral stenosis affects interpretation tables of the
ipsilateral internal carotid artery's degree of stenosis in duplex Doppler ultrasound, the …

Optimal criteria for the duplex sonographic diagnosis of carotid artery stenosis have not yet
been defined. We studied 205 vessels in 105 patients with both duplex sonography and …

The accuracy, rapidity, and reproducibility of color-Doppler-assisted duplex sonography in
the diagnosis of significant internal carotid artery stenosis were prospectively evaluated …

High-resolution duplex sonography was compared with biplane magnified carotid
angiography in a prospective evaluation of 161 carotid arteries in 86 patients. The duplex …

Duplex ultrasonography combining high‐resolution imaging and Doppler spectrum analysis
was performed in 92 consecutive patients (total, 180 vessels) and compared with the …

Materials and Methods Using an ATL Mark V Duplex sonographic unit (Advanced
Technology Labs., Bellevue, WA), we evaluated the carotid arteries of about 250 patients in …

Oculoplethysmography-carotid phonoangiography and periorbital directional Doppler
sonography are two techniques widely used in the noninvasive evaluation of possible …

Carotid artery disease was assessed in 180 patients by means of color Doppler flow
imaging. Color Doppler findings in 360 carotid arteries were compared with the results of …

Duplex sonography is a relatively new technique for noninvasive evaluation of the
extracranial carotid arteries. In a prospective, double‐blind study of 453 vessels (229 …
