FMRI Approaches to Mapping Cerebrovascular Reactivity: Comparison of Gradient Echo BOLD and Spin Echo BOLD With Arterial Spin Labeling

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To compare markers of cerebrovascular reactivity (CVR) measured with Gradient Echo (GE, T2*w) and Spin‐Echo (SE, T2w) BOLD fMRI with quantitative physiological CVR measured using ASL. Methods CVR, the ability of blood vessels to dilate and increase cerebral blood flow (CBF), can be investigated with ASL fMRI but has a low signal‐to ...

Pulse Pressure, White Matter Hyperintensities, and Cognition: Mediating Effects Across the Adult Lifespan

Annals of Clinical and Translational Neurology
Objectives To investigate whether pulse pressure or mean arterial pressure mediates the relationship between age and white matter hyperintensity load and to examine the mediating effect of white matter hyperintensities on cognition.

Clinically Feasible White Matter Fiber Tractography in Peritumoral Zones With Cerebral Vasogenic Edema

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In diffusion MRI, vasogenic edema manifests as a major fraction of isotropic water that dilutes the anisotropic intra‐axonal portion of the signal. Many tractography algorithms mistake vasogenic edema for the white matter boundary and terminate tracking to prevent producing spurious streamlines.

Phenotyping Overactive Bladder—Part 1: Are There Different Types of Urgency and Can They be Translated to Clinical, Urodynamic and Radiological Phenotyping? ICI‐RS 2025

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction Overactive bladder (OAB) is defined as urinary urgency, usually accompanied by increased daytime frequency and/or nocturia, with urgency urinary incontinence (OAB‐wet) or without (OAB‐dry), in the absence of urinary tract infection or other detectable disease.

Kaposiform hemangioendothelioma: Diagnosis and treatment

Pediatric Investigation, EarlyView.
Vascular endothelial growth factor‐C (VEGF‐C)/vascular endothelial growth factor receptor‐3 (VEGFR‐3) and angiopoietin‐2 (Ang‐2)/tyrosine kinase with immunoglobulin‐like and EGF‐like domain 2 (TIE2) signaling pathways play an important role in lymphangiogenesis.

Predictors of Complete Oral Intake in Patients With Stroke After Tracheostomy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Tracheostomy procedures inhibit swallowing, although details of subsequent recovery of oral intake remain unknown. This retrospective cohort study aimed to investigate factors influencing dysphagia improvement in patients with subacute stroke ...

MRI‐based qualitative, quantitative, and radiomics/deep learning methods for assessing treatment response after neoadjuvant chemoradiotherapy in patients with locally advanced rectal cancer

Precision Radiation Oncology, EarlyView.
MRI, owing to its superior soft tissue contrast and spatial resolution, has become the preferred noninvasive modality for assessing nCRT efficacy. This review synthesizes current evidence on MRI‐based assessment of nCRT efficacy in LARC and discusses future directions.
