MRI findings in posttraumatic stress disorder - PubMed
Magnetic resonance imaging (MRI) plays a primary role in both structural and functional neuroimaging for PTSD, demonstrating focal atrophy of the gray matter, altered fractional anisotropy, and altered focal neural activity and functional connectivity.
Neuroimaging of posttraumatic stress disorder in adults and …
2024年4月17日 · This review will examine structural and functional magnetic resonance imaging (MRI) literature using univariate, bivariate, and network-based approaches in adult and youth PTSD populations.
Neuroimaging in Posttraumatic Stress Disorder and Other Stress …
Several studies have found smaller anterior cingulate volumes based on MRI measurements in PTSD [97–99], including women with abuse and PTSD . One study found a reduction in the ratio of NAA to creatinine (Cr) measured with magnetic resonance spectroscopy [ 79 ], while another found a decrease in gray matter density [ 100 ].
Neuroimaging of posttraumatic stress disorder in adults and …
Structural MRI of PTSD populations typically determines alterations in the morphometry of brain regions in patients versus controls (trauma-exposed non-PTSD [TENC] or healthy controls [HC]). Morphometric measures include subcortical and cortical gray matter volumes, thickness, and white matter microstructure.
Functional neuroimaging studies of post-traumatic stress disorder
In order to investigate the neurocircuitry of PTSD, researchers have used functional MRI (fMRI), SPECT and PET.
MRI findings in posttraumatic stress disorder - Kunimatsu - 2020 ...
Magnetic resonance imaging (MRI) plays a primary role in both structural and functional neuroimaging for PTSD, demonstrating focal atrophy of the gray matter, altered fractional anisotropy, and altered focal neural activity and functional connectivity.
Neuroimaging findings in post-traumatic stress disorder
Computed tomography studies were first to suggest brain abnormalities in PTSD and there have been eight reports on magnetic resonance imaging (MRI) studies in subjects with PTSD .
Meta-Analysis of 89 Structural MRI Studies in Posttraumatic
2018年10月1日 · Objective: The authors conducted a comprehensive meta-analysis of MRI region-of-interest and voxel-based morphometry (VBM) studies in posttraumatic stress disorder (PTSD). Because patients have high rates of comorbid depression, an additional objective was to compare the findings to a meta-analysis of MRI studies in depression.
Prognostic neuroimaging biomarkers of trauma-related
2021年1月21日 · Magnetic resonance imaging (MRI) data from 109 recently (i.e., ~2 weeks) traumatized individuals were collected and PTSD and depression symptoms were assessed...
Mapping PTSD symptoms to brain networks: a machine learning study …
2020年6月18日 · We acquired resting-state magnetic resonance imaging in a sample (N = 50) of PTSD patients and characterized clinical features using the PTSD Checklist for DSM-5 (PCL-5).
