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...
متن کاملestimation of carotid artery pulse wave velocity by doppler ultrasonography
background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...

Introduction: Digital Subtraction Angiography (DSA) is the standard method for detection of carotid artery stenosis. This technique has high radiation dose. With the progress of imaging techniques, noninvasive or minimally invasive methods like the CT angiography, MR angiography and ultrasonography with Doppler or Duplex mode were applicable. This study aimed to evaluate and assesse the results...
متن کاملRadiologic importance of a high-resistive vertebral artery Doppler waveform on carotid duplex ultrasonography.
OBJECTIVE The appearance of the vertebral artery (VA) waveform on a pulsed Doppler examination performed during standard carotid duplex ultrasonography (CDU) may suggest vertebrobasilar disease. We sought to determine the radiographic importance of high-resistive (HR) pulsed Doppler VA waveforms seen on CDU. METHODS The Noninvasive Vascular Laboratory database was queried for CDU studies noti...
متن کاملDiagnostic performance of duplex ultrasonography in the detection of high grade internal carotid artery stenosis.
OBJECTIVES to establish on a national basis whether the diagnostic accuracy of carotid duplex justifies carotid surgery without preoperative angiography. DESIGN prospective national multicentre study with 10 participating university and county hospitals. MATERIAL AND METHODS one hundred and thirty-four patients, aged 69+/-9 years, were subjected to routine carotid duplex ultrasonography and...
