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

Movement 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

Movement 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 ...

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

Movement 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.

Gene Therapy for Amino Acid Decarboxylase Deficiency: Clinical and Imaging Outcomes in a French Cohort

Movement Disorders, EarlyView.
Abstract Background Intracerebral gene therapy is effective for amino acid decarboxylase (AADC) deficiency, but relationships between anatomical putaminal coverage, metabolic dynamics, and clinical recovery remain poorly understood. Objectives Assess safety, long‐term efficacy, and clinical–radiological correlations in a genetically diverse European ...

Key Interventions in Friedreich's Ataxia and Their Impact on Patient Outcomes: A Systematic Review

Movement Disorders, EarlyView.
Abstract Friedreich's ataxia (FA) is a rare neurodegenerative disease with multisystemic symptoms that requires multidisciplinary care. This systematic review summarizes available pharmacological and nonpharmacological interventions, their outcomes, and alignment with patient‐centered care domains, as well as their impact on these domains.

View Order With Arbitrary Center Echoes

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

Free‐Breathing Hepatic Oxygen Extraction Fraction (OEF) Mapping Using Radial GESSE

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Noninvasive assessment of hepatic oxygenation is relevant for evaluating liver both in acute and long‐term liver pathologies. However, existing methods are limited to single‐slice acquisitions and require breath‐holding. This study aims to develop and evaluate a motion‐robust technique for whole‐liver oxygen extraction fraction (OEF ...
