Electroencephalogram Electrode and Amplifier Temperature Changes During Routine Anatomical and Functional Magnetic Resonance Imaging Sequences at 3 Tesla Open
Magnetic resonance imaging (MRI) sequences commonly used in simultaneous electroencephalogram (EEG)-MRI studies include blood oxygenation level-dependent (BOLD) and anatomical T 1 -weighted MRI. Safety and electrode heating profiles for th…

Chronic active lesions preferentially localize in watershed territories in multiple sclerosis Open
Objective Paramagnetic rim lesions (PRLs) are a biomarker of chronic active lesions (CALs), and an important driver of neurological disability in multiple sclerosis (MS). The reason subtending some acute lesions evolvement into CALs is not…

Detectability of white matter cerebral blood flow using arterial spin labeling MRI in patients with sickle cell disease: Relevance of flow territory, bolus arrival time and hematocrit Open
Sickle cell disease (SCD) is the most common genetic blood disorder, characterized by red cell hemolysis, anemia, and corresponding increased compensatory cerebral blood flow (CBF). SCD patients are at high risk for cerebral infarcts and C…

Reduced cerebrospinal fluid motion in patients with Parkinson’s disease revealed by magnetic resonance imaging with low b-value diffusion weighted imaging Open
Background Parkinson’s disease is characterized by dopamine-responsive symptoms as well as aggregation of α-synuclein protofibrils. New diagnostic methods assess α-synuclein aggregation characteristics from cerebrospinal fluid (CSF) and re…

Deep learning segmentation of the choroid plexus from structural magnetic resonance imaging (MRI): validation and normative ranges across the adult lifespan Open
Background The choroid plexus functions as the blood-cerebrospinal fluid (CSF) barrier, plays an important role in CSF production and circulation, and has gained increased attention in light of the recent elucidation of CSF circulation dys…

Watershed regions are more susceptible to tissue microstructural injury in multiple sclerosis Open
Histopathologic studies report higher concentrations of multiple sclerosis white matter lesions in watershed areas of the brain, suggesting that areas with relatively lower oxygen levels may be more vulnerable to disease. However, it is un…

Choroid plexus vascular reactivity in moyamoya: Implications for choroid plexus regulation in ischemic stress Open
Background and Purpose Choroid plexus (ChP) hyperemia has been observed in patients with intracranial vasculopathy and to reduce following successful surgical revascularization. This observation may be attributable to impaired vascular res…

Deep learning segmentation of the choroid plexus from structural magnetic resonance imaging (MRI): validation and normative ranges across the adult lifespan Open
Background : The choroid plexus functions as the blood-cerebrospinal fluid barrier, plays an important role in neurofluid production and circulation, and has gained increased attention in light of the recent elucidation of neurofluid circu…

Reduced suprasellar cistern cerebrospinal fluid motion in patients with Parkinson’s disease revealed by magnetic resonance imaging with dynamic cycling of diffusion weightings Open
BACKGROUND: Parkinson’s disease is characterized by dopamine-responsive symptoms as well as aggregation and accumulation of a-synuclein protofibrils. New diagnostic methods assess a-synuclein aggregation characteristics from cerebrospinal …

Cerebrospinal Fluid Flow in Patients with Huntington's Disease Open
Objective Investigations of cerebrospinal fluid (CSF) flow aberrations in Huntington's disease (HD) are of growing interest, as impaired CSF flow may contribute to mutant Huntington retention and observed heterogeneous responsiveness to in…

Parasagittal dural space hypertrophy and amyloid-β deposition in Alzheimer’s disease Open
One of the pathological hallmarks of Alzheimer’s and related diseases is the increased accumulation of protein amyloid-β in the brain parenchyma. As such, recent studies have focused on characterizing protein and related clearance pathways…
View article: Choroid plexus perfusion and bulk cerebrospinal fluid flow across the adult lifespan
Choroid plexus perfusion and bulk cerebrospinal fluid flow across the adult lifespan Open
The choroid plexus (ChP) comprises a collection of modified ependymal cells that play an important role in the production of brain cerebrospinal fluid (CSF), and ChP perfusion aberrations have been implicated in a range of cerebrovascular …

Parasagittal Dural Space and Cerebrospinal Fluid (CSF) Changes Across the Lifespan in Healthy Adults: Implications for Glymphatic Flow Open
Background: Recent studies have suggested the importance of a glymphatic clearance pathway for brain parenchymal metabolic waste products. One fundamental but relatively under-explored component of this pathway is the anatomic region surro…
