Objectives: Atherosclerotic stenosis of the middle cerebral artery (MCA) is one of the causes
of ischemic stroke, but aside from investigations using magnetic resonance angiography …

Atherosclerotic lesions of the extracranial cerebral arteries account for ischemic stroke in
over half of all cases. The risk of stroke associated with symptomatic carotid artery disease is …

Abstract Purpose Transcranial Doppler sonography (TCD) is commonly used for the
diagnosis of middle cerebral artery (MCA) stenosis. However, TCD indices to predict distal …

ABSTRACT BACKGROUND AND PURPOSE Transcranial Doppler (TCD) criteria for
cerebrovascular stenosis are only based on velocity with unsatisfactory positive predictive …

Background. Patients with 50% intracranial arterial stenosis may require more intensive
therapies for stroke prevention. Transcranial Doppler (TCD) is a convenient noninvasive …

BACKGROUND AND PURPOSE: Stroke risk of asymptomatic atherosclerotic middle
cerebral artery (MCA) stenosis has not been well studied. This study was designed to …

Objective To evaluate the best cutoff points of flow velocity for diagnosing and grading
middle cerebral artery (MCA) stenosis as compared with magnetic resonance angiography …

ABSTRACT Background and Purpose. Magnetic resonance imaging (MRI) has been widely
applied in detecting intracranial large artery stenosis, but there have been few validation …

Stroke is one of the most common neurological disorders with a high incidence in Middle-
eastern regions. We aimed to assess the diagnostic accuracy of neurovascular ultrasound to …

Objectives Routine sonography of the middle cerebral artery in acute ischemic stroke
usually focuses on the main stem (M1 segment). However, stenoses and occlusions affect …
