Postprandial Changes in Thoracic Aortic Flow Detected by 4D Flow MRI May Influence Study Results

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background While there is a growing body of data using 4D flow MRI to distinguish between normal and abnormal blood flow values in the thoracic aorta, the extent of physiological variation or lack thereof is potentially undervalued. Physiological processes such as postprandial changes to hemodynamics might influence data, normal values, follow‐

Response to Letter to the Editor: Impact of 1024‐Matrix Size on Perforating Artery Visualization in Cerebral CTA Using a 64‐Slice CT Scanner

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This response addresses a Letter to the Editor commenting on our article on 1024‐matrix reconstruction for perforating artery visualisation in cerebral CTA using a 64‐slice CT scanner (https://doi.org/10.1002/jmrs.70055). It acknowledges that integration with iterative or deep‐learning reconstruction, workflow and PACS burden, and downstream clinical ...

3D quantitative MRI for cognitive performance: T1 relaxation times of the right putamen and volumes of the left hippocampus as key biomarkers

open access: yesNeuroImage: Reports
Background: Mild cognitive impairment (MCI) represents anearly stage of cognitive decline, often preceding dementia. While hippocampal atrophy is a recognized imaging marker, the role of deep gray matter structures and tissue alterations remains less ...

Quantitative Assessment of Visible Nigrosome‐1 in Patients with Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background The nigrosome‐1 (N1) sign on susceptibility‐weighted imaging (SWI) typically disappears in Parkinson's disease (PD), though some patients can show uni−/bilaterally preserved N1. Objective Investigating whether visible nigrosomes in PD patients differ from those of healthy subjects (HC). Methods Forty‐eight PD and 35 HC underwent 3 T‐

A Severity‐Agnostic Atrophy Pattern in Spinocerebellar Ataxia Type 3: Volumetrics from ENIGMA‐Ataxia

open access: yesMovement Disorders, EarlyView.
Background Spinocerebellar ataxia type 3 (SCA3) is a rare, inherited neurodegenerative disease characterized by progressive loss of motor coordination. Objectives We undertook a multisite magnetic resonance imaging study to profile the spatial spread of atrophy across the brain, determine whether atrophy preferentially maps onto specific functional ...

Evaluating brain and lens radiation exposure in interventional neuroradiology

open access: yesPhysica Medica
This study evaluated brain and lens radiation doses during interventional neuroradiology (INR) procedures, focusing on cumulative mean organ absorbed doses and risks of exceeding dose thresholds for tissue reactions.A retrospective audit of adult INR procedures from January 2018 to June 2024 at a tertiary centre.

Plasma p‐tau217 Versus p‐tau181 in Parkinson's Disease: Differential Associations with Alzheimer's Disease‐Related Neurostructural Changes and Cognitive Function

open access: yesMovement Disorders, EarlyView.
Abstract Background Plasma phosphorylated‐tau at threonine‐217 (p‐tau217) and threonine‐181 (p‐tau181) are scalable, minimally invasive biomarkers of Alzheimer's disease (AD) pathology. In Parkinson's disease (PD), AD co‐pathology may contribute to its clinical heterogeneity.
