Arterial Spin Labeling MRI in Alzheimer’s Disease: A Systematic Review of Cerebral Perfusion Biomarkers

by Clinical Neuropsychologist | Saturday, March 15, 2025 | Neuroimaging

ABSTRACT Background Alzheimer’s disease (AD) is a leading cause of dementia. Arterial spin labeling (ASL) MRI, particularly at 3 Tesla (3T), offers a noninvasive method to assess cerebral blood flow alterations, which are believed to be early indicators of AD....

Resting‐State fMRI to Map Language Function for Surgical Planning in Patients With Brain Tumors: A Feasibility Study

by Clinical Neuropsychologist | Wednesday, February 26, 2025 | Neuroimaging

ABSTRACT Background and Purpose In neurosurgery, functional MRI is crucial for preoperative planning to obtain the cortical cortex map of language areas. This preliminary work involved analyzing the functional MRIs of 20 oncological patients. Our question is if...

Myelin Quantification Using Ultrashort Echo Time Magnetization Transfer Ratio in a Mouse Model of Traumatic Brain Injury

by Clinical Neuropsychologist | Tuesday, February 25, 2025 | Neuroimaging

ABSTRACT Background and Purpose This study aims to assess the potential of ultrashort echo time imaging-based magnetization transfer ratio (UTE-MTR) in detecting demyelination in mice with mild traumatic brain injury (mTBI) caused by an open-field low-intensity blast...

Blood Flow Velocities as Determined by Real‐Time Phase‐Contrast MRI in Patients With Carotid Artery Stenosis

by Clinical Neuropsychologist | Tuesday, February 25, 2025 | Neuroimaging

ABSTRACT Background and Purpose Real-time phase-contrast (RT-PC) flow MRI can be used to determine quantitative flow parameters throughout the vessel lumen of extracranial, brain-supplying arteries. Its potential value in the diagnostic workup of patients with carotid...

Hippocampal Subfield Abnormalities in Patients With Primary Trigeminal Neuralgia

by Clinical Neuropsychologist | Wednesday, February 19, 2025 | Neuroimaging

ABSTRACT Background and Purpose Primary trigeminal neuralgia (PTN) is a prevalent chronic pain disorder whose pathogenesis is not solely confined to the trigeminal system. Although substantial progress has been made in understanding the underlying mechanisms,...

High‐Field Diffusion Tensor Imaging of Median, Tibial, and Sural Nerves in Type 2 Diabetes With Morphometric Analysis

by Clinical Neuropsychologist | Tuesday, February 18, 2025 | Neuroimaging

ABSTRACT Background and Purpose The primary objective was to compare diffusion tensor imaging (DTI) scalar parameters of peripheral nerves between subjects with type 2 diabetes mellitus (T2DM) and those without diabetes. Secondarily, we aimed to correlate DTI scalar...
