Magnetic resonance imaging (MRI) is an imaging technique which physicians use for the diagnosis and treatment of medical conditions.

Rapid progression of multiple sclerosis linked to smoking

Patients with multiple sclerosis who smoke appear to experience a more rapid progression of their disease, according to a report in the July issue of Archives of Neurology, one of the JAMA/Archives journals.

New findings on molecular imaging and prostate cancer

A new study published in the September issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed.

New method found for the diagnosis of cartilage disease

In its quest to find new strategies to treat osteoarthritis and other diseases, a Boston University-led research team has reported finding a new computer tomography contrast agent for visualizing the special distributions of glycosaminoglycans (GAGs) - the anionic sugars that account for the strength of joint cartilage.

Caltech neuroscientists emphasize on the neural mechanisms involved in social behaviour

In a finding that sheds new light on the neural mechanisms involved in social behavior, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space.

Astrocytes play a key role in the generation of fMRI signals

Functional magnetic resonance imaging (fMRI) is a technique widely used in studying the human brain. However, it has long been unclear exactly how fMRI signals are generated at brain cell level. This information is crucially important to interpreting these imaging signals. Scientists from the Academy of Finland's Neuroscience Research Programme (NEURO) have discovered that astrocytes, support cells in brain tissue, play a key role in the generation of fMRI signals.

Research finds that people with psoriasis are less likely to react to looks of disgust by others

People with psoriasis - an often distressing dermatological condition that causes lesions and red scaly patches on the skin - are less likely to react to looks of disgust by others than people without the condition, new research has found.

Adolescents engaged in dangerous activities are associated with increased brain maturity

A new study using brain imaging to study teen behavior indicates that adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers.

Toshiba America Medical Systems installs its 800th Vantage 1.5T MR system

Toshiba America Medical Systems, Inc., an industry leader in magnetic resonance (MR) technology, reached a significant achievement in installing its 800th Vantage 1.5T MR system at Elkview General Hospital in Hobart, Okla. Elkview is using the Vantage system for orthopedic, neuro and abdominal imaging.

New minimally invasive surgery techniques and instruments reduce tissue damage and infection

New, delicate surgery techniques to hunt for tumours could benefit from a lighter touch - but from a robot, rather than from a human hand. Canadian researchers have created a touchy-feely robot that detects tougher tumour tissue in half the time, and with 40% more accuracy than a human. The technique also minimises tissue damage.

Depression causes reduced function in the reward center of brain

Clinically depressed individuals are less capable of finding pleasure in activities they previously enjoyed, a recent study has proven. Research featured in the August 26 issue of the NeuroReport shows reduced brain function in the reward center of the brain in depressed individuals, when compared to healthy subjects.

Genentech announces Phase III study results for Avastin (bevacizumab) in combination with chemo in HER2-negative breast cancer

Genentech, Inc. today announced that a Phase III study (RIBBON 2) of Avastin (bevacizumab) in combination with chemotherapy increased the time women with metastatic HER2-negative breast cancer whose initial chemotherapy had stopped working lived without the disease worsening (progression-free survival or PFS), compared to chemotherapy alone.

Tiny magnetic particles guide stem cells to damaged tissue

Microscopic magnetic particles have been used to bring stem cells to sites of cardiovascular injury in a new method designed to increase the capacity of cells to repair damaged tissue, UCL scientists announced today.

FDA approves Extavia for multiple sclerosis

The US Food and Drug Administration (FDA) has approved Extavia(R) (interferon beta-1b), the first in a new planned portfolio of multiple sclerosis (MS) medicines from Novartis to help patients manage this devastating disease.

MRI increases chances of more extensive surgery over conservative approaches in breast cancer diagnosis

A new review says using magnetic resonance imaging (MRI) before surgery to assess the extent of early breast cancer has not been shown to improve surgical planning, reduce follow-up surgery, or reduce the risk of local recurrences.

Sleep patterns can identify adolescents at greatest risk for depression

Sleep patterns can help predict which adolescents might be at greatest risk for developing depression, a researcher at UT Southwestern Medical Center has found in a five-year study.

Similarities found in the way neural circuits linked to vision process information in both sighted and blind since birth

The ability to recognize visually presented objects relies on a critical neural pathway called the ventral stream. Previous imaging studies of the human brain have demonstrated that the sight of nonliving objects, such as tools and houses, activates different regions within the ventral stream than the sight of living things, such as animals and faces. It is not known whether category-specific neural responses in the ventral stream depend on visual experience.

Alcoholics display abnormal brain activity when processing facial expressions

Researchers from Boston University School of Medicine (BUSM) have found that individuals who have a long history of alcoholism, but who have been abstinent for at least a month up to many years, showed abnormal brain activity when looking at facial expressions of others.

Education impacts cognitive function in Alzheimer's disease

Researchers at the Department of Psychiatry, Klinikum rechts der Isar, Technische Universität München, investigated the effects of formal education on the symptoms of Alzheimer's disease. They were able to show that education diminishes the impact of Alzheimer's disease on cognition even if a manifest brain volume loss has already occurred.

Gallbladder emptying in primary sclerosing cholangitis patients

Primary sclerosing cholangitis (PSC) is an idiopathic chronic cholestatic inflammatory liver disease characterized by diffuse fibrosing inflammation of intra- and/or extrahepatic bile ducts, resulting in bile duct obliteration, biliary cirrhosis, and eventually hepatic failure. One of the most common symptoms at the time of presentation of PSC is mild to severe abdominal pain localized in the right upper quadrant. However, the mechanisms responsible for the abdominal pain in PSC are not fully understood.
