Altered orbitofrontal sulcogyral pattern in schizophrenia
(Oxford University Press (OUP), 2007)Orbitofrontal alteration in schizophrenia has not been well characterized, likely due to marked anatomical variability. To investigate the presence of such alterations, we evaluated the sulcogyral pattern of this ‘H-shaped’ ... -
Amygdala–hippocampal shape differences in schizophrenia: the application of 3D shape models to volumetric MR data
(Elsevier BV, 2002)Evidence suggests that some structural brain abnormalities in schizophrenia are neurodevelopmental in origin. There is also growing evidence to suggest that shape deformations in brain structure may reflect abnormalities ... -
Automated Decision-Support System for Prediction of Treatment Responders in Acute Ischemic Stroke
(Frontiers Media S.A., 2013)MRI is widely used in the assessment of acute ischemic stroke. In particular, it identifies the mismatch between hypoperfused and the permanently damaged tissue, the PWI-DWI mismatch volume. It is used to help triage ... -
Blood pool contrast agents for venous magnetic resonance imaging
(AME Publishing Company, 2016)Imaging of the venous system plays a vital role in the diagnosis and management of a wide range of clinically significant disorders. There have been great advances in venous imaging techniques, culminating in the use of ... -
Cavum septi pellucidi in first-episode schizophrenia and first-episode affective psychosis: an MRI study
(Elsevier BV, 2004)A high prevalence of abnormal cavum septi pellucidi (CSP) in schizophrenia may reflect neurodevelopmental abnormalities in midline structures of the brain. The relationship, however, between abnormal CSP and clinical ... -
Cavum septum pellucidum in monozygotic twins discordant for combat exposure: relationship to posttraumatic stress disorder
(Elsevier BV, 2004)Background Abnormally large cavum septum pellucidum has been reported in posttraumatic stress disorder; however, the origin of this association is uncertain. Methods: We utilized magnetic resonance imaging to measure ... -
Circulating Omega‐3 Polyunsaturated Fatty Acids and Subclinical Brain Abnormalities on MRI in Older Adults: The Cardiovascular Health Study
(Blackwell Publishing Ltd, 2013)Background: Consumption of tuna or other broiled or baked fish, but not fried fish, is associated with fewer subclinical brain abnormalities on magnetic resonance imaging (MRI). We investigated the association between ... -
Clarifying the Origin of Biological Abnormalities in PTSD Through the Study of Identical Twins Discordant for Combat Exposure
(Wiley-Blackwell, 2006)A biological abnormality found to be associated with post-traumatic stress disorder (PTSD) may be, among other things, a pre-trauma vulnerability factor, that is, it may have been present prior to the event’s occurrence ... -
CNTNAP2 polymorphisms and structural brain connectivity: A diffusion-tensor imaging study
(Elsevier BV, 2013)CNTNAP2 is a gene on chromosome 7 that has shown associations with autism andschizophrenia, and there is evidence that it plays an important role for neuronal synchronization and brain connectivity. In this study, we ... -
Combining ERP and Structural MRI Information in First Episode Schizophrenia and Bipolar Disorder
(SAGE Publications, 2008)The electrical activity in the electroencephalogram (EEG) and the event-related potentials extracted from the EEG provide the greatest temporal resolution for examining brain function. When coupled with the high spatial ... -
Data Sharing In Neuroimaging Research
(Frontiers Research Foundation, 2012)Significant resources around the world have been invested in neuroimaging studies of brain function and disease. Easier access to this large body of work should have profound impact on research in cognitive neuroscience ... -
Dense, shape‐optimized posterior 32‐channel coil for submillimeter functional imaging of visual cortex at 3T
(John Wiley and Sons Inc., 2015)Purpose Functional neuroimaging of small cortical patches such as columns is essential for testing computational models of vision, but imaging from cortical columns at conventional 3T fields is exceedingly difficult. By ... -
Diagnosis of Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia: Proposed Modification of the Task Force Criteria
(Ovid Technologies (Wolters Kluwer Health), 2010)Background: In 1994, an International Task Force proposed criteria for the clinical diagnosis of ARVC/D which facilitated recognition and interpretation of the frequently non-specific clinical features of ARVC/D. This ... -
Differential Recovery of Glycosaminoglycan After IL-1-Induced Degradation of Bovine Articular Cartilage Depends on Degree of Degradation
(BioMed Central, 2003)In the present study we examined cartilage matrix repair following IL-1-induced matrix depletion. Previous data indicated that, in some cases, chondrocytes can synthesize macromolecules to establish a functional extracellular ... -
Diffusion MRI of Structural Brain Plasticity Induced by a Learning and Memory Task
(Public Library of Science, 2011)Background: Activity-induced structural remodeling of dendritic spines and glial cells was recently proposed as an important factor in neuroplasticity and suggested to accompany the induction of long-term potentiation ... -
Diffusion MRI quality control and functional diffusion map results in ACRIN 6677/RTOG 0625: A multicenter, randomized, phase II trial of bevacizumab and chemotherapy in recurrent glioblastoma
(D.A. Spandidos, 2015)Functional diffusion mapping (fDM) is a cancer imaging technique that quantifies voxelwise changes in apparent diffusion coefficient (ADC). Previous studies have shown value of fDMs in bevacizumab therapy for recurrent ... -
Dynamic 1H-MRS assessment of brain tumors: A novel approach for differential diagnosis of glioma
(Impact Journals LLC, 2015)Purpose To determine whether the changes of [Cho/NAA] ratio in patients with glioma, measured by dynamic 1H-MRS can be used to differentiate between high-grade and low-grade gliomas. Materials and Methods This prospective ... -
Evidence for Acquired Pregenual Anterior Cingulate Gray Matter Loss from a Twin Study of Combat-Related Posttraumatic Stress Disorder
(Elsevier BV, 2008)Background Controversy exists over the nature and origin of reduced regional brain volumes in posttraumatic stress disorder (PTSD). At issue is whether these reductions represent preexisting vulnerability factors for ... -
