The Role of Neurosonology in the Diagnosis and Management of Patients with Carotid Artery Disease: A Review
ABSTRACT Carotid artery disease (CAD) is a common cause of ischemic stroke with high rates of recurrence. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are highly recommended for the secondary prevention of symptomatic CAD during the first 14 days following the index event of transient ischemic attack or minor stroke. CEA or CAS may also be offered in selected cases with severe asymptomatic stenosis. Herein, we review the utility of neurosonology in the diagnosis and pre‐/peri‐interventional assessment of CAD patients who undergo carotid revascularization procedures. Carotid ultrasound may provide inval...

Hypointense Vessels Detected by Susceptibility ‐Weighted Imaging Identifies Tissue at Risk of Infarction in Anterior Circulation Stroke
CONCLUSIONVisual analysis of HV in SWI identifies tissue at risk in patients with anterior circulation stroke. Potentially pre‐existing extracranial ICA occlusions leading to prominent HV have to be considered as a confounding factor.

Characteristics of Accredited Transcranial Doppler Ultrasound Laboratories in the United States
CONCLUSIONSThe results suggest that there are significant differences between IAC applicant laboratories and laboratories represented by Centers for Medicaid and Medicare Services (CMS) claims data. In addition, accurate study reporting, physician training, and ongoing quality improvement activities may not be optimized in laboratories applying for accreditation. With the information learned from this study, educational strategies by professional organizations, including the IAC, can be tailored to help improve TCD practice.

Etiology of Intracranial Arterial Stenosis: Are Transcranial Color‐Coded Duplex Ultrasound and 3T Black Blood MR Imaging Complementary?
CONCLUSIONSThese two combined imaging techniques might be promising for the differentiation of arteriosclerotic changes from stenosis of another origin, especially when follow‐up TCCD studies are completed early before a possible regression of the atherosclerotic plaque that might be observed 6 months after initial diagnosis.

Detection of Right‐to‐Left Cardiac Shunt in the Absence of Transcranial Acoustic Bone
CONCLUSIONSWhen transcranial acoustic bone windows are missing, Doppler ultrasound of the cervical submandibular ICA and VAs are valid screening methods to detect RLS due to a PFO.

Evaluation of Rotational Vertebral Artery Occlusion Using Ultrasound Facilitates the Detection of Arterial Dissection in the Atlas Loop
CONCLUSIONFor posterior circulation stroke patients, adding submaximal head rotation to the cervical ultrasound examination facilitated the detection of VAD in the atlas loop.

Vascular Imaging Before Intravenous Thrombolysis: Consequences of In‐Hospital Delay in Applying Two Diagnostic Procedures
CONCLUSIONSPerforming CTA before IVT seems to increase door‐to‐needle time. Vascular imaging based on DUS should be considered only if this does not lead to in‐hospital delay.

Internal Carotid Artery Floating Thrombus in Relapsing Polychondritis
We present a 52‐year‐old man without any known risk factors for stroke, treated with prednisone and azathioprine for relapsing polychondritis, who presented a minor left hemisphere stroke. Ultrasound of the neck vessels revealed an isoechogenic thrombus in the left internal carotid artery superimposed on a smooth moderately stenosing isoechogenic atheroma of the carotid bulb. The patient was treated with high‐dose tinzaparin and was followed with serial ultrasound. After 16 days, the thrombus demonstrated a hypoechogenic core surrounded by a hyperechogenic rim and the following day it resolved completely. Thrombus fo...
