It is of crucial importance to predict the presence of stenosis in cerebral artery before
occurrence of a stroke. To determine stenosis in the middle cerebral artery (MCA), we …

The main limitation of transcranial colour-coded duplex sonography (TCCD) is the
inadequate acoustic window, which prevents transtemporal identification of the basal …

Background and purpose. To investigate the optimal values of flow velocity on transcranial
Doppler (TCD) in grading the severity of middle cerebral artery (MCA) stenosis in …

Magnetic resonance angiography (MRA) findings of uni-or bilateral middle cerebral artery
(MCA) stenosis were compared with results of transcranial Doppler ultrasound (TCD) and …

Intracranial atherosclerotic disease is increasingly recognized as a major stroke subtype
worldwide. Current diagnostic evaluation of atherosclerotic disease of the middle cerebral …

BACKGROUND AND PURPOSE: Atherothrombotic disease of the middle cerebral artery
(MCA) frequently occurs in Asian populations. This abnormality can be noninvasively …

ABSTRACT Background and Purpose. This study was designed to assess the accuracy of
transcranial color‐coded sonography (TCCS) as compared to magnetic resonance …

Background and Purpose Magnetic resonance angiography and computed tomography
angiography are new, noninvasive methods to provide images of the cerebral vasculature …

OBJECTIVE: To detect the display rate and flow velocity of intracranial circle of Willis
(anterior, middle, and posterior cerebral arteries) with transcranial contrast-enhanced …
