Overcoming pitfalls in multi-stack diffusion MRI for tractography reconstruction of skeletal muscles

Manuela Zimmer, Geoffrey Handsfield, Paul Condron, Samantha Holdsworth et autres

Accurate in vivo characterization of skeletal muscle structure is essential for understanding muscle function, assessing pathologies, and developing musculoskeletal models. Magnetic resonance imaging (MRI) and diffusion MRI enable visualization of muscle morphology and fibre architecture in vivo, but imaging skeletal muscles often …

Multimodal MRI Reveals Brain Structural Differences and Executive Dysfunction in Early Methamphetamine Abstinence

Ben Bristow, Maryam Tayebi, Paul Condron, Taylor Emsden et autres

BACKGROUND: Methamphetamine use disorder (MUD) is known to have profound effects on brain structure and cognitive functions. Understanding the extent of these neurobiological changes during the early abstinence period is crucial for developing targeted rehabilitation strategies. OBJECTIVE: This study aimed to investigate …

Whiteout sign on dSIR MRI: A case series highlighting symptom-associated white matter changes not observed on standard T 2 -FLAIR

Joshua P. McGeown, Gil Newburn, Paul Condron, Samantha J Holdsworth et autres

INTRODUCTION: Mild traumatic brain injury (mTBI) is common, and up to half of patients experience persistent symptoms, but conventional neuroimaging typically appears normal. Divided Subtracted Inversion Recovery (dSIR) is a new sequence with high sensitivity to white matter changes that may appear …

Ultra-high contrast MRI of the brain and spinal cord using directly acquired and synthetic BipoLAr Inversion Recovery (BLAIR) images

Daniel Cornfeld, Paul Condron, Mark Bydder, Tracy R. Melzer et autres

Abstract: Ultra-high contrast (UHC) magnetic resonance imaging (MRI) is a term used to describe magnetic resonance (MR) imaging that shows abnormalities with high contrast when little or no abnormality is seen on common conventional state-of-the-art MR images. It is achieved without the …

Pulsatile Brain Motion as a Marker of Brain Aging and Dementia: Insights from 3D q-aMRI

Itamar Terem, Kyan Younes, Andrew M. Dreisbach, Hillary A. Vossler et autres

Heart-brain interactions, including cardiac-induced brain pulsatility, are thought to support brain homeostasis, yet their alteration with aging and neurodegeneration remains poorly understood. Here, we used three-dimensional quantitative amplified MRI (q-aMRI) to visualize and quantify cardiac-induced pulsatile brain motion across healthy individuals and …

Neuroimaging correlates of symptom burden and functional recovery following mild traumatic brain injury: A systematic review

Joshua P. McGeown, Mangor Pedersen, Remika Mito, Alice Theadom et autres

BACKGROUND: Mild traumatic brain injury (mTBI) represents 95% of all traumatic brain injuries. Despite being classified as "mild," mTBI can lead to persistent symptoms that impact quality of life. Diagnostic and management strategies rely heavily on subjective symptom reporting due to a …

The Role of Incidental Magnetization Transfer in Divided Subtracted Inversion Recovery

Mark Bydder, Olivier M. Girard, Tracy R. Melzer, Paul Condron et autres

ABSTRACT Divided subtracted inversion recovery (dSIR) images show abnormal changes in the white matter of the brain in patients with mild traumatic brain injury (mTBI) due to an increase in the apparent T 1 compared to normal controls. The present study aims …

The role of incidental magnetization transfer in divided subtracted inversion recovery

Mark Bydder, Tracy R. Melzer, Nickolas J. Palmer, Paul Condron et autres

Motivation: The dSIR sequence shows changes in mTBI patients that have not been seen previously that correspond to a small difference in T1. The motivation of the study is to understand the origin of the signal changes. Goal(s): The goal is to …

Ultra-High Contrast (UHC) MRI with bipolar filters: Obvious abnormalities in normal appearing brain, spinal cord and optic nerve

Paul Condron, Daniel Cornfeld, Mark Bydder, Taylor Emsden et autres

Motivation: Many standard MRI brain scans fail to depict abnormalities in patients despite obvious findings in their clinical presentation. This can lead to negative health and social consequences. Goal(s): Using ultra-high contrast (UHC) MRI we aimed to improve detection of subtle pathological …
