Article Abstract
Objectives: The 2010 revisions to the McDonald criteria for the diagnosis of multiple sclerosis (MS) were recently published. One objective of the revision was to simplify the MRI criteria. The MRI criteria do not specify magnetic field strength. We studied whether there was any difference in diagnosis between brain 3.0-T and 1.5-T MRI according to the 2010 revisions of the McDonald criteria.
Patients And Methods: We prospectively studied brain 3.0-T and 1.5-T MRI in 22 patients with MS. 1.5-T MRI was performed 24h after 3.0-T MRI, and the scanning protocol included contiguous axial sections of T2-weighted images (T2WI), T1WI, and enhanced T1WI. These two different MRI and neurological assessments were scheduled to be repeated 3 and 6 months after study entry.
Results: The regions where MS lesions were better visualized on 3.0-T MRI tended to be in deep white matter on T2WI. Dissemination of lesions in space and time was similar for 3.0-T and 1.5-T MRI.
Conclusion: Our study found no difference between brain 3.0-T and 1.5-T MRI. There was no apparent impact of brain 3.0-T MRI on the diagnosis of MS according to the 2010 version of the MRI criteria.

Cognitive Outcomes in Myelin Oligodendrocyte Glycoprotein-IgG Associated Disease Compared to Multiple Sclerosis.
Brain Behav
March 2025
Mellen Center for Multiple Sclerosis, Neurological Institute Cleveland Clinic, Cleveland, Ohio, USA.
Background: Little is known about cognitive outcomes in people with myelin oligodendrocyte glycoprotein-IgG associated disease (pwMOGAD). While there are similarities between MOGAD and multiple sclerosis (MS), further evaluation is needed to establish the distinct cognitive trajectories for each disease.
Methods: Retrospective review of subjective cognitive changes was performed for adult pwMOGAD.
Optimization and validation of low-field MP2RAGE T mapping on 0.35T MR-Linac: Toward adaptive dose painting with hypoxia biomarkers.

Background: Stereotactic MR-guided Adaptive Radiation Therapy (SMART) dose painting for hypoxia has potential to improve treatment outcomes, but clinical implementation on low-field MR-Linac faces substantial challenges due to dramatically lower signal-to-noise ratio (SNR) characteristics. While quantitative MRI and T mapping of hypoxia biomarkers show promise, T-to-noise ratio (TNR) optimization at low fields is paramount, particularly for the clinical implementation of oxygen-enhanced (OE)-MRI. The 3D Magnetization Prepared (2) Rapid Gradient Echo (MP2RAGE) sequence stands out for its ability to acquire homogeneous T-weighted contrast images with simultaneous T mapping.

Introduction: The aim of this study was to investigate the role of sacubitril/valsartan in managing hypertension and cardiac remodeling in patients undergoing hemodialysis.
Methods: Hemodialysis patients with stable blood pressure control were enrolled in the study. Sacubitril/valsartan was prescribed to replace previously used angiotensin-converting enzyme inhibitor/angiotensin receptor blocker or other antihypertensive drugs.
A neuroimaging measure to capture heterogeneous patterns of atrophy in Parkinson's disease and dementia with Lewy bodies.

Introduction: Parkinson's disease (PD) and Dementia with Lewy bodies (DLB) show heterogeneous brain atrophy patterns which group-average analyses fail to capture. Neuroanatomical normative modelling overcomes this by comparing individuals to a large reference cohort. Patient-specific atrophy patterns are measured objectively and summarised to index overall neurodegeneration (the 'total outlier count').

Individuals who have experienced more trauma throughout their life have a heightened risk of developing posttraumatic stress disorder (PTSD) following injury. Although trauma history cannot be retroactively modified, identifying the mechanism(s) by which preinjury life events influence future PTSD symptoms may help clinicians mitigate the detrimental effects of past adversity. The current study proposed attributional negativity bias, the tendency to perceive stimuli/events as negative, as a potential intermediary in PTSD development.
