Teleneurosonology: A Novel Application of Transcranial and Carotid Ultrasound
To demonstrate the technical feasibility of interfacing transcranial Doppler (TCD) and carotid “duplex” ultrasonography (CUS) peripherals with telemedicine end points to provide real-time spectral waveform and duplex imaging data for remote review and interpretation.

Detection of Basilar Artery Dissection by Ultrasound
We report a case of a 45-year-old woman with unusual headache 1 week before admission. After cerebrovascular ultrasound, a basilar artery dissection was supposed despite the normal neurologic, cerebrospinal fluid, and computed tomography findings. On a follow-up color-coded duplex sonography (1 month after the onset), reperfusion was detected in the vertebral and basilar arteries, but residual high-grade stenosis of the basilar artery was also present.

Cranioplasty and Duraplasty with Transcranial Color-Coded Duplex Sonography after Aneurysmal Subarachnoid Hemorrhage
Transcranial color-coded duplex sonography (TCCS) is a noninvasive technique for monitoring of cerebral vasospasm after neurosurgery for aneurismal subarachnoid hemorrhage. In this surgery, surgical materials are used. The goal of the study was to identify materials that can be used with ultrasound and to propose methods for cranioplasty and duraplasty using materials that permit TCCS.

In this study, we evaluated the microembolic signals (MES) frequency with transcranial Doppler ultrasound (TCD) in patients with atrial fibrillation (AF) under anticoagulant therapy, and we compared the treatment groups.

Characteristics of Cerebral Hemodynamics in Patients with Ischemic Leukoaraiosis and New Ultrasound Indices of Ischemic Leukoaraiosis
The diagnosis of ischemic leukoaraiosis (ILA) is based on head magnetic resonance imaging (MRI) and exclusion of other causes of white matter hyperintensities (WMHs). Recent studies have shown increased arterial stiffness and diminished carotid flow in ILA patients. So far, there are very little data on intracerebral hemodynamic parameters in ILA. Due to the specific structure of the intracranial arteries, our aim was to investigate intracerebral hemodynamic parameters in ILA patients and, possibly, to find a reliable ultrasound index of combined intra- and extracranial cerebral arteries.

Ultrasound Tissue Pulsatility Imaging Suggests Impairment in Global Brain Pulsatility and Small Vessels in Elderly Patients with Orthostatic Hypotension
Orthostatic hypotension (OH) is highly prevalent in the elderly, and this population can be exposed to serious complications, including falls and cognitive disorders, as well as overall mortality. However, the pathophysiology of OH is still poorly understood, and innovative methods of cerebral blood flow (CBF) assessment have been required to accurately investigate cerebrovascular reactivity in OH.

Comparison of Three-Dimensional T1-Weighted Magnetic Resonance and Contrast-Enhanced Ultrasound Plaque Images for Severe Stenosis of the Cervical Carotid Artery
Magnetic resonance (MR) and contrast-enhanced ultrasound assess characteristics and neovascularization, respectively, of the carotid plaque. The purpose of the present study was to clarify how findings of contrast-enhanced ultrasound plaque imaging are related to those of 3-dimensional (3D) fast spin echo (FSE) T1-weighted MR plaque imaging (WI) in severe stenosis ( ≥70%) of the cervical carotid artery.

Evaluation of the Time-Dependent Changes and the Vulnerability of Carotid Plaques Using Contrast-Enhanced Carotid Ultrasonography
The association of carotid plaque enhancement on contrast-enhanced carotid ultrasound (CEUS) and plaque vulnerability evaluated by magnetic resonance imaging (MRI) was to be determined.

Ultrasound-Mediated Kallidinogenase-Loaded Microbubble Targeted Therapy for Acute Cerebral Infarction
This study was designed to investigate the optimal parameters for preparing kallidinogenase-loaded microbubbles (KLMs) and to evaluate the effects of KLM-targeted therapy on neurogenesis and angiogenesis following experimental acute cerebral infarction in rats.

Transorbital Sonography to Evaluate Optic Nerve in Hypertensive Encephalopathy
We read with great interest the article by Kitano et  al concerning a case of hypertensive encephalopathy with enlarged optic nerve sheath diameter (ONSD) measured by ultrasound (US).1

In Response to: De Bernardo, M and Rosa, N. “Transorbital Sonography to Evaluate Optic Nerve in Hypertensive Encephalopathy”
We thank Bernardo and Rosa for their interest in our recent publication about optic nerve sheath diameter (ONSD) measurement by ultrasound (US).1 Their comments gave us further insight into this method. They mentioned 2 concerns about our case: first, that measurements by B-scan are not sensitive enough to detect slight changes in ONSD, and, second, that measurements in our case did not appropriately evaluate the same portion.

Detection of Subclinical Atherosclerosis in Subclavian Arteries of Subjects with Vascular Risk Factors and Normal Carotid Ultrasound
Most risk scores that use imaging methods to determine the presence of subclinical atherosclerosis assess the carotid and coronary arteries. The value of assessing subclavian arteries to improve the predictive capacity of traditional imaging studies is not known.

Platelet Aggregability as a Predictor of Restenosis Following Carotid Endarterectomy
Background: Antiplatelet drugs are administered before and after carotid endarterectomies (CEAs), but their efficacy for preventing restenosis remains unclear. Hence, this study aimed to identify associations between postoperative restenosis and platelet aggregability in CEA patients. Methods: Thirty-six consecutive CEA patients treated at Tokyo Women's Medical University from May 2013 to March 2015 were included in this retrospective study. Restenosis was defined as a stenosis ratio greater than or equal to 50% per the European Carotid Surgery Trial criteria or peak systolic velocity of 150 cm/s on carotid ultrasound.
