Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose We aim to assess the reliability of cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) obtained simultaneously from a novel multi‐band pseudo‐continuous arterial spin labeling (M2‐PCASL) sequence and hypercapnic gas challenge, to examine factors influencing CBF variability, and to evaluate the impact of carbon dioxide (CO2)

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To directly quantify respiration‐driven cerebrovascular resistance dynamics (CRD) using a gas‐free MRI framework based on the internal‐to‐external artery carotid flow ratio (ratio_Q). Theory and Methods Two independent datasets (n = 10 and n = 17) were used to evaluate repeatability and to compare breathing conditions.

Blood flow dynamics in patient specific arterial network in head and neck [PDF]
, 2011 This paper shows a steady simulation of blood flow in the major head and neck arteries as if they had rigid walls, using patient specific geometry and CFD software FLUENT R .

Otolaryngology–Head and Neck Surgery, EarlyView.Abstract Objective Non‐echo‐planar diffusion‐weighted imaging (non‐EPI DWI) magnetic resonance imaging (MRI) has revolutionized postoperative cholesteatoma follow‐up, shifting from surgical to radiological evaluation. Yet, the timing for postoperative imaging remains contentious.

Neuromodulation: Technology at the Neural Interface, EarlyView., 2020 Abstract Objectives While preliminary evidence suggests that noninvasive vagal nerve stimulation (nVNS) may enhance cognition, to our knowledge, no study has directly assessed the effects of nVNS on brain function and cognitive performance in healthy individuals.

Vascular Supply of Laryngeal Paragangliomas: Case Report and Systematic Review
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objective Laryngeal paragangliomas are rare, highly vascularized, neuroendocrine tumors. Although surgical resection of these vascular neoplasms is associated with a known risk of significant hemorrhage, the vascular supply of laryngeal paragangliomas has been poorly characterized. Data Sources MEDLINE Ovid, Embase, Scopus, and Google Scholar.

The baroreceptor reflex emanating from the carotid sinus and common carotid artery of the sheep : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Physiology at Massey University [PDF]
, 1987 The aim of this project was to improve understanding of the role of the common carotid arterial baroreceptor mechanism in controlling peripheral blood pressure in the sheep.

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objectives For intraoperative bleeding control in patients with juvenile nasopharyngeal angiofibroma (JNA), we developed a novel surgical strategy system. This system is focused on feeding artery management, based on the spatial relationship between the tumor entity and feeding artery as determined by three‐dimensional reconstruction.
