In the unconscious patient, there is a diagnostic void between the neurologic physical exam,
and more invasive, costly and potentially harmful investigations. Transcranial color-coded …

Objective Reversible cerebral vasoconstriction syndromes (RCVS) are characterized by
thunderclap headaches and reversible cerebral vasoconstrictions. No systematic studies on …

Transcranial color-coded duplex ultrasonography (TCCS) enables the visualization of basal
cerebral arteries through the intact skull by color-coding of blood flow velocity. The arteries …

Introduction: Reversible cerebral vasoconstriction syndrome (RCVS) typically affects young
patients and left untreated can result in hemorrhage or ischemic stroke. Though the disorder …

Dramatic hemodynamic changes occur following resection of brain arteriovenous
malformations (AVM). Transcranial Doppler (TCD) records non-invasive velocity and …

BACKGROUND AND PURPOSE: Gradation of high-grade intracranial internal carotid artery
(ICA) stenosis poses a challenge to noninvasive neurovascular imaging, which seems …

Introduction The purpose of the present study was to investigate normal ranges and test-
retest reproducibility of phase-contrast MRI (PC-MRI)-measured flow and velocity …

Objective To explore age-related cerebral hemodynamic characteristics before and after
pediatric cardiac surgery. Design Prospective observational study. Setting Single-center …

Background and Purpose—It is unclear which harmonic imaging mode (power Doppler or
gray-scale imaging) is superior and which measuring method is the most robust for the …

BACKGROUND AND PURPOSE: Disturbance of the autonomic nervous system (ANS) is
frequently encountered in Parkinson's disease (PD). In this study, we examined changes in …
