Doppler Sonography of Opthalmic Artery for the Screening of Ischemic Internal Carotid Artery Disease.

Noninvasive Angiography for the Diagnosis of Carotid Artery Disease Using Doppler Ultrasound (Carotid Artery Doppler)

To detect stenosis in the carotid artery with a bidirectional continuous-wave Doppler ultrasound device, the following noninvasive procedure, applied on 800 patients and compared with 249 angiograms of 186 patients, has proved to be about 90% reliable. Measurements of flow signals were taken over the terminal branches of the ophthalmic artery (supratrochlear and supraorbital arteries) and avera...

A Penetrating Pellet Jeopardizing Internal Carotid Artery

Diagnosis of internal carotid artery stenosis greater than 70% with power Doppler duplex sonography.

BACKGROUND AND PURPOSE Duplex sonography is an effective tool for evaluating internal carotid artery (ICA) stenosis, and power Doppler imaging has improved its value in this regard. Our goal was to elucidate which parameters, such as linear stenosis, area stenosis, and peak systolic velocity (PSV), are the most reliable predictors of ICA stenosis greater than 70% using the method proposed by th...

Three-dimensional color Doppler sonography in carotid artery stenosis.

BACKGROUND AND PURPOSE Color Doppler sonography (CDS) suffers from such disadvantages as high interobserver variability and problems with data presentation and storage. We therefore performed a prospective trial to assess the role of three-dimensional CDS (3D-CDS) in the evaluation of internal carotid artery stenosis (ICAS). METHODS We included 32 consecutive patients with sonographically ver...
