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...
متن کاملThree-dimensional assessment of extracranial Doppler sonography in carotid artery stenosis compared with digital subtraction angiography.
BACKGROUND AND PURPOSE Difficulties in data presentation, data storage, and a high interobserver variability may influence color-coded Duplex sonography assessment of internal carotid artery stenosis (ICAS). The aim of our study was to evaluate the between-method agreement of ICAS using 3D color Doppler sonography (CDS) compared with digital subtraction angiography (DSA). METHODS Forty-nine p...
متن کاملDiagnosis 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...
متن کاملDiagnosing carotid stenosis by Doppler sonography: state of the art.
OBJECTIVE The goal of this review article is to present the state of the art in the clinical applications and technical performance and interpretation of carotid sonographic examinations. METHODS Relevant publications regarding color and duplex Doppler sonography (CDDS) of the carotid arteries extracted from a computerized database (MEDLINE) and from references cited in these articles not app...
متن کاملDoppler Sonography in the Detection of Significant Renal Artery Stenosis
Background Systemic hypertension is a major risk factor both for stroke and for myocardial infarction. The search for underlying treatable cause is a part of the management of a hypertensive patient. Renal vascular hypertension is the most common form of potentially curable hypertension and if untreated may terminate in renal failure. It has been estimated that 10% to 20% of new patients presen...
