Genetic predictors of hippocampal subfield volume in PTSD cases and trauma-exposed controls

European Journal of Psychotraumatology, 2020
Behavioural, structural, and functional neuroimaging have implicated the hippocampus as a critical brain region in posttraumatic stress disorder (PTSD) pathogenesis. Recent work in a normative, primarily European, sample identified 15 unique genetic loci

Role of structural MRI in Alzheimer's disease [PDF]

Alzheimer's Research & Therapy, 2010
Atrophy measured on structural magnetic resonance imaging (sMRI) is a powerful biomarker of the stage and intensity of the neurodegenerative aspect of Alzheimer's disease (AD) pathology. In this review, we will discuss the role of sMRI as an AD biomarker by summarizing (a) the most commonly used methods to extract information from sMRI images, (b) the ...

How Inflammation Affects the Brain in Depression: A Review of Functional and Structural MRI Studies

Journal of Clinical Neurology, 2021
This narrative review discusses how peripheral and central inflammation processes affect brain function and structure in depression, and reports on recent peripheral inflammatory marker-based functional and structural magnetic resonance imaging (MRI ...

Quantification of amyloid beta and tau PET without a structural MRI

Alzheimer's & Dementia, 2022
Relying on magnetic resonance imaging (MRI) for quantification of positron emission tomography (PET) images may limit generalizability of the results. We evaluated several MRI‐free approaches for amyloid beta (Aβ) and tau PET quantification relative to ...

Predicting ‘Brainage’ in late childhood to adolescence (6-17yrs) using structural MRI, morphometric similarity, and machine learning

Scientific Reports, 2023
Brain development is regularly studied using structural MRI. Recently, studies have used a combination of statistical learning and large-scale imaging databases of healthy children to predict an individual’s age from structural MRI.

Learning-based analysis of amide proton transfer-weighted MRI to identify true progression in glioma patients

NeuroImage: Clinical, 2022
The purpose of this study was to develop and verify a convolutional neural network (CNN)-based deep-learning algorithm to identify tumor progression versus response by adding amide proton transfer-weighted (APTw) MRI data to structural MR images as the ...

The clinical use of structural MRI in Alzheimer disease

Nature Reviews Neurology, 2010
Structural imaging based on magnetic resonance is an integral part of the clinical assessment of patients with suspected Alzheimer dementia. Prospective data on the natural history of change in structural markers from preclinical to overt stages of ...

Data-Driven Definitions for Active and Structural MRI Lesions in the Sacroiliac Joint in Spondyloarthritis and their Predictive Utility.

Rheumatology, 2021
OBJECTIVES To determine quantitative sacroiliac joint (SIJ) MRI lesion cut-offs that optimally define a positive MRI for inflammatory and structural lesions typical of axial spondyloarthritis (axSpA) and that predict clinical diagnosis.

Assessment of calvarial structure motion by MRI [PDF]

Osteopathic Medicine and Primary Care, 2009
Practitioners of manual medicine/manual therapy (MM/MT) who utilize techniques thought to have some impact upon and move the solid structures of the human head have been criticized for lack of evidence of cranial bone motion. The present study utilized magnetic resonance imagery (MRI) technology to address the question of whether or not inherent (non ...

Structural MRI in Autism Spectrum Disorder [PDF]

Pediatric Research, 2011
Magnetic resonance (MR) examination provides a powerful tool for investigating brain structural changes in children with autism spectrum disorder (ASD). We review recent advances in the understanding of structural MR correlates of ASD. We summarize findings from studies based on voxel-based morphometry, surface-based morphometry, tensor-based ...
