We analyzed carotid duplex ultrasound (CDU) in DeBakey I acute aortic dissection to identify characteristics and establish a protocol to ensure appropriate evaluation. Method.€" From 2002 to 2011, patients with CDU and proximal aortic dissection were identified. The protocol included color Doppler ...
Evaluation of carotid arteries and plaques in this region by means of PW and color Doppler has been useful up to date to diagnose carotid disease and its degree of severity and define treatment strategies. However, some limitations due to plaque characteristics like length, tortuosity, heterogeneity...
Carotid Doppler Velocity Measurements and Anatomic Stenosis: Correlation Is Futile Background: Duplex ultrasound with Doppler velocimetry is widely used to evaluate the presence and severity of internal carotid artery stenosis; however, a...

The Society of Radiologists in Ultrasound convened a multidisciplinary panel of experts in the field of vascular ultrasonography (US) to come to a consensus regarding Doppler US for assistance in the diagnosis of carotid artery stenosis. The panel's consensus statement is believed to represent a re...

Spectral Doppler waveforms are obtained with a defined technique; the waveforms should be obtained by placing the cursor in the longitudinal view of the artery with the cursor placed in the center of the stream of flow, the “flow jet.” The recommended Doppler angle is between 40 and 60 ...
AIM: To compare the accuracy of ultrasound and two magnetic resonance (MR) angiographic techniques with catheter angiography in assessing atherosclerosis at the carotid bifurcation. MATERIALS AND METHODS: Forty patients with symptomatic carotid stenosis were studied by Doppler ultrasound, time-of-flight MR...

A fast-track neurovascular ultrasound examination [6] with high accuracy in detecting arterial lesions, can be integrated in the hyperacute stroke workflow and facilitate revascularization therapies (Table 1). The typical CDU protocol begins with gray-scale (B-Mode) images of CCA and ICA in ...
The laboratory evaluation of a patient with suspected ischemic monocular visual loss begins with noninvasive assessment of the carotid artery using either ultrasound, magnetic resonance angiography (MRA), or computed tomography angiography (CTA). Carotid ultrasound and Doppler (Fig. 10.4) are effective ...
