The aim of this thesis is to create a product, in the form of a handbook, for patients undergoing conventional radiography or ultrasound examinations general

The exctracranial carotid plaques are easily accessible to noninvasive ultrasonic evaluation and CT. Transcranial Doppler (TCD) is a noninvasive ultrasound

Methods: Carotid angiograms performed at the completion of CAS were compared with duplex ultrasound (DUS) imaging performed immediately after the procedure. Patients were followed up with annual DUS imaging and underwent both ultrasound scans and computed tomography angiography (CTA) at their most recent follow-up visit. Background and Purpose— To evaluate duplex ultrasonographic thresholds for the determination of 70% to 99% stenosis of the ipsilateral and contralateral internal carotid artery in patients with symptoms of amaurosis fugax, transient ischemic attack (TIA), or minor stroke based on 2 criteria: maximizing accuracy and optimizing cost-effectiveness and to compare these with current recommendations. Ultrasound assessment of carotid arterial atherosclerotic disease has become the first choice for carotid artery stenosis screening, permitting the evaluation of both the macroscopic appearance of plaques as well as flow characteristics in the carotid artery.

This scan uses two types of ultrasound to provide an accurate picture of the blood vessels as well as show how blood is flowing through them. Carotid artery ultrasound duplex assessment is non-invasive and easy to perform, although it requires high technical skills and is not really specific . Studies regarding the routine screening of ICA stenosis and the use of carotid artery ultrasound duplex in all adult patients undergoing cardiac surgery have conflicting opinions [7,8,12,13,15-20] . 1.1 What is carotid (duplex) ultrasound? Carotid ultrasound (also called carotid duplex sonography or scan) is one of the most important ultrasound imaging modalities in medicine. It allows us to assess cerebrovascular risk and diseases such as: carotid plaques , carotid artery obstruction (stenosis) and many other pathologies (i.e.

Fig. 2: Types of carotid Carotid artery ultrasounds are used to assess the extracranial carotid arteries for the presence of stenosis and to determine the direction of blood flow.
