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

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 …

This review considers the capabilities and limitations of duplex sonography in the diagnosis
of abnormalities of the cerebral vasculature. Duplex sonography is an elegant union of B …

The duplex ultrasonic scanner combines real-time B-mode imaging with a single-gate,
variable-range pulsed Doppler. The detection and categorization of the severity of carotid …

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 …

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 …

Both carotid bifurcations were examined in 353 patients over a 20-month interval using a
combination of real-time and pulsed Doppler ultrasound (duplex scanning). Angiographic …

Duplex sonography is the best noninvasive modality for investigation of possible carotid
artery stenosis. By using the above described techniques, almost all significant stenoses can …

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