Association Between Gas‐Free Cerebrovascular Reactivity (CVR) and Cognitive Function in Older Adults With a High Risk for Vascular Dementia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia. Cerebrovascular reactivity (CVR) is a promising biomarker for VCID. However, CVR is not commonly measured in clinical practice due to logistical difficulties in applying a hypercapnia challenge during MR imaging. Purpose To investigate whether

White coat hypertension is associated with increased small vessel disease in the brain [PDF]

, 2019
Objective: Small vessel disease, as measured by white matter hyperintensity (WMH) in the brain, is known to be associated with increased stroke risk and cognitive impairment.

Subjective Cognitive Decline Is Associated with Greater White Matter Hyperintensity Volume

Journal of Alzheimer's Disease, 2018
Background: Research in older adults with subjective cognitive decline (SCD) has mainly focused on Alzheimer’s disease (AD)-related MRI markers, such as hippocampal volume.

Pulsatility Assessment of Cerebral Perforating Arteries Using Submillimeter‐Resolution Dual‐VENC Phase‐Contrast MRI at 3T

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dysfunction of cerebral perforating arteries is a major contributor to cerebral small vessel disease. Developing a reliable MRI technique for assessing cerebral perforating arteries on widely accessible 3T systems would be advantageous.

Cognitive Impact of Lacunar Infarcts and White Matter Hyperintensity Volume

Dementia and Geriatric Cognitive Disorders Extra, 2015
Background: Subcortical lacunar infarcts and white matter hyperintensities (WMH) are common neuroradiological findings, but few studies associate between these insults and cognition in a community-dwelling population. Methods: The Dallas Heart Study is a

White matter hyperintensity lesion burden is associated with the infarct volume and 90‐day outcome in small subcortical infarcts

Acta Neurologica Scandinavica, 2017
Small subcortical infarcts (SSI) frequently coexist with brain white matter hyperintensity (WMH) lesions. We sought to determine whether preexisting WMH burden relates to SSI volume, SSI etiology, and 90‐day functional outcome.

Clinical Applications of Electrical Conductivity Imaging Using MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Magnetic resonance imaging (MRI) has emerged as a noninvasive technique for probing the electrical properties of biological tissues: electrical conductivity and relative permittivity. This review focuses on the electrical conductivity and provides a comprehensive overview of applications across both low‐ and high‐frequency regimes.

Managing the meniscus part I—Anatomy, biomechanics, and treatment strategies for the atraumatic meniscus tear

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The purpose of this article is to serve as the first of a two‐part review on the meniscus; in this review, we will establish the background on anatomy and pathogenesis of the meniscus, as well as the effect of the meniscus on native knee kinematics and function.
