Normal individuals who scored high on a measure of impulsive/antisocial traits display a hypersensitive brain reward system, according to a neuroradiology study published online March 14 in the journal Nature Neuroscience.
Researchers at Duke University in Durham, N.C., have used functional MRI to demonstrate how people make decisions about attractiveness and what that attractiveness is worth. The research was published online Feb. 16 in the Journal of Neuroscience.
By way of functional MRI (fMRI), researchers from the Imaging Institute at the University of Texas Health Science Center in San Antonio were able to observe the default-mode network-0a neural network in the brain--and determine that genetics have an effect on this and several other networks.
A combined technique utilizing functional MRI and mental-imagery tasks have proven that a small proportion of patients diagnosed as being in a vegetative or minimally conscious state may have brain activity reflecting some awareness and cognition, according to the results of a study published online Feb. 3 in the New England Journal of Medicine.
Researchers have reportedly identified a biological marker in the brains of those exhibiting post-traumatic stress disorder using magnetoencephalography (MEG), based on a study published Jan. 20 in the Journal of Neural Engineering.
Post-traumatic stress symptoms may present a neurofunctional marker of decreased activity of the hippocampus in youth with a history of interpersonal trauma, said a new study's lead author Victor Carrion, MD, child psychiatrist and associate professor of the department of psychiatry and behavioral sciences at Stanford University in Calif., and his colleagues.
Intra-amygdala abnormalities and engagement of a compensatory frontoparietal executive control network, which are cognitive theories of generalized anxiety disorders (GADs) were consistent with the findings of a study published in the December edition of Archives of General Psychiatry, which studied the functional connectivity at a subregional level in the human brain that may mark GADs.
A study published in the December issue of the Journal of the American College of Radiology shows that 95 percent of radiation oncologists incorporated advanced imaging technologies, such as MRI, PET, SPECT, 4DCT, functional MRI and MR spectroscopy, into radiation therapy planning.
Optoacoustics (Booth 1202) is introducing its new dual-channel optical microphone for functional MRI (fMRI) environments, the FOMRI-III, at the 2009 Radiological Society of North America (RSNA) meeting in Chicago this month.
Resonance Technology of Northridge, Calif., an MRI-compatible technology company, is introducing a new entertainment delivery system for the MRI environment, as well as a high-resolution functional MRI (fMRI) panel at the 2009 Radiological Society of North America (RSNA) conference.
Seiji Ogawa, PhD, of the Hamano Life Science Research Foundation in Tokyo, who discovered that MRI could be used to measure oxygen flow in the brain in real time, making functional MRI (fMRI) possible, has been named as a possible winner of the 2009 Nobel Prize by researchers at Thomson Scientific, the science unit of Thomson Reuters.
A difference in brain activity patterns may explain why some people are able to maintain a significant weight loss while others regain the weight, according to a functional MRI (fMRI) study published last month in the American Journal of Clinical Nutrition.
In a functional MRI (fMRI) study, neurologists and psychiatrists at Columbia University in New York City have identified an area of the brain involved in the earliest stages of schizophrenia and related psychotic disorders, according to findings published Monday in the Archives of General Psychiatry.
Researchers, using whole-brain event-related functional MRI, have determined that a low-effort, high-accuracy memory activation task is sensitive to Alzheimer's disease risk factors, such as family history and apolipoprotein E e4.
Ducking a punch calls for the human brain to process 3D motion; thus, perceiving an object that is moving in three dimensions is critical to survival, according to findings published online in Nature Neuroscience earlier this month.
A new technology involving the fusion of four different types of images to create a 3D brain map has helped University of Cincinnati physicians remove a fist-sized tumor from the brain of an Indiana woman.

Medical imaging overutilization--a growing concern in the U.S.--exposes patients to unnecessary radiation, while also adding to rising healthcare costs, according to a study published online Aug. 24 in Radiology. In an interview, William R. Hendee, PhD, lead author, reviewed various methods by which medical imaging could be curtailed.
Dedicated contrast-enhanced (CE) breast CT delivered significantly improved conspicuity of malignant breast lesions, including ductal carcinoma in situ (DCIS), compared with unenhanced breast CT and mammography, according to a study published in the September issue of Radiology.
CT, ultrasound and MRI have helped shift biopsy techniques away from more invasive approaches toward image-guided percutaneous techniques, according to a study published in the September issue of Radiology. The trend toward less-invasive approaches translates into enhanced safety and efficiency and could lead to more interaction between patients and radiologists.
The Centers for Medicare & Medicaid Services’ (CMS) EHR incentive payments are not considered reimbursement for money expended on EHR technology, but are intended to offset the cost associated with adoption and ongoing meaningful use, according to CMS during an Aug. 12 webinar.
Funding incentives for EHR use is the main goal of the Centers for Medicare & Medicaid Services' (CMS) meaningful use initiative, and there are incentive programs for both hospitals and eligible professionals, according to Elizabeth Holland, health insurance specialist at the Department of Health and Human Services, who spoke during a CMS-sponsored webinar Aug. 8.
Stage 1 requirements for meaningful use incentives aim to strike a balance between the overall goal of EHR use and widespread adoption, while avoiding added work, said Jonathan Teich, MD, PhD, chief medical informatics officer at Elsevier Health Services, during a HIMSS webinar titled “Meaningful Use: Safety and Quality of Care.”
