Quantitative MRI Evaluation of Hemispheric Asymmetry in Circle of Willis Artery Diameters

by Clinical Neuropsychologist | Wednesday, February 4, 2026 | Neuroimaging

ABSTRACT Background Previous studies have identified hemispheric asymmetries in cerebral blood flow and volume, favoring the left hemisphere. Accordingly, we hypothesized that arteries on the left side of the circle of Willis (CoW) are larger than on the right. We...

T1w/T2w Ratio Identifies the Basolateral Amygdala as a Preferential Target in Autoimmune Limbic Encephalitis

by Clinical Neuropsychologist | Thursday, January 22, 2026 | Neuroimaging

ABSTRACT Background and Purpose The amygdala plays a key role in the pathophysiology of autoimmune limbic encephalitis (ALE), contributing to epileptic seizures and neuropsychiatric symptoms. While no study has examined microstructural changes in individual amygdala...

Explainable Machine‐Learning Model to Classify Culprit Calcified Carotid Plaque in Embolic Stroke of Undetermined Source

by Clinical Neuropsychologist | Thursday, January 22, 2026 | Neuroimaging

ABSTRACT Background and Purpose Embolic stroke of undetermined source (ESUS) may be associated with carotid artery plaques with <50% stenosis. Plaque vulnerability is multifactorial, possibly related to intraplaque hemorrhage (IPH), lipid-rich necrotic core,...

Brain Microstructural Damage as Potential Biomarker of Immune Cell‐Associated Neurotoxicity Syndrome

by Clinical Neuropsychologist | Saturday, January 17, 2026 | Neuroimaging

ABSTRACT Background and Purpose Chimeric antigen receptor–engineered T-cell (CAR-T) therapy in hematological malignancies may be associated with severe complications, as Cytokine Release Syndrome (CRS) and Immune effector Cell-Associated Neurotoxicity Syndrome...

Diffusion Kurtosis Shows a Smaller Ischemic Core Versus Diffusion‐Weighted MR in Early or Subacute Post‐Thrombectomy Stroke

by Clinical Neuropsychologist | Friday, December 19, 2025 | Neuroimaging

ABSTRACT Background and Purpose Diffusion-weighted imaging (DWI) is the gold standard for assessing ischemic core in acute stroke but may overestimate irreversible injury due to its assumption of Gaussian diffusion. Diffusion kurtosis imaging (DKI), which accounts for...

Subregional Amygdala Functional Connectivity at 3T: Comparison of High‐Resolution 2D and 3D fMRI Acquisitions

by Clinical Neuropsychologist | Wednesday, December 17, 2025 | Neuroimaging

ABSTRACT Background and Purpose Amygdala dysfunction is implicated in major depressive disorder. Despite wide acknowledgement of its heterogeneity, the amygdala is predominantly considered as a single entity and functional connectivity investigations have reported...
