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

Functional MRI can detect pathological foetal brain defects earlier in the womb

A team of researchers at the MedUni's Clinical Department of Neuroradiology and Musculoskeletal Radiology has demonstrated for the first time ever that there are foetal brain developments that can be measured using functional magnetic resonance tomography in the womb.

Physicians can do better if they learn from their failures

When seeking a physician, you should look for one with experience. Right? Maybe not. Research on physicians' decision-making processes has revealed that those who pay attention to failures as well as successes become more adept at selecting the correct treatment.

Imaging is about finding the most appropriate way to assess heart disease

"The idea is that we're using the most appropriate technology to address individual clinical questions rather than just focusing on one technique," explains EAE President Dr Luigi Badano, from the University of Padua, Italy.

Study shows degeneration of corpus callosum in stroke patients with impaired hand movement

The structure of the corpus callosum, a thick band of nerve fibres that connects the two halves of the brain with each other and in this way enables the rapid exchange of information between the left and right hemispheres, plays an important role in the regaining of motor skills following a stroke. A study currently published in the journal Human Brain Mapping has shown that in stroke patients with particularly severely impaired hand movement, this communication channel between the two brain hemispheres in particular was badly damaged.

Genetic basis of human cortical regionalization similar to patterns found in other mammals, MRI study affirms

A new study using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization - the organization of the outer brain into specific functional areas - is similar to and consistent with patterns found in other mammals, indicating a common conservation mechanism in evolution.

Study uses MRI to evaluate cardiovascular risk in WTC first responders

In the first study using magnetic resonance imaging (MRI) to evaluate cardiovascular risk in World Trade Center (WTC) first responders, researchers from Mount Sinai School of Medicine have found that the responders who experienced high levels of exposure to the initial dust cloud on September 11, 2001, demonstrate high-risk features of atherosclerosis.

Head hits appear to cause brain injury among high school players

The brain scans of high school football and hockey players showed subtle injury -- even if they did not suffer a concussion - after taking routine hits to the head during the normal course of play, according to a University of Rochester Medical Center study.

Study: Primary visual cortex is modulated only by attention

In everyday life, attention and awareness appear tightly interwoven. Attending to the scissors on the rinumber of behavioural observations have recently led scientists to postulate that attention and awareness are fundamentally different processes and not necessarily connected.ght side of your desk, you become aware of their attributes, for example the red handles. Vice versa, the red handles could attract your attention to the scissors.

Vegetative patients could be contacted using simple, cheap and portable technique – EEG

Scientists from the UK and Belgium have found a way to communicate with brain damaged patients who appear to be in a vegetative state. Writing in The Lancet medical journal they describe how they measured electrical activity in the brain to detect consciousness. The technique, known as EEG or electroencephalogram, is painless and involves attaching electrodes to the head.

Experimental drug selectively destroys blood supply of fat tissue and decreases body fat

Obese rhesus monkeys lost on average 11 percent of their body weight after four weeks of treatment with an experimental drug that selectively destroys the blood supply of fat tissue, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in Science Translational Medicine.

Simple portable test can diagnose 'vegetative' patients with consciousness

The Coma Science Group, led by Dr Steven Laureys, has developed, along with its partners in London, Ontario, (Canada) and Cambridge (England), a portable test which will permit a simpler and less expensive diagnosis of 'vegetative' patients who still have consciousness, despite the fact that they do not have the means to express it.

Study: Children with autism have more prefrontal brain neurons

In a small, preliminary study that included 13 male children, those with autism had an average 67 percent more prefrontal brain neurons and larger than average brain weight, than children without autism, according to a study in the Nov. 9 issue of JAMA.

Study finds spinal bleeding in young children with abusive head trauma

A new study found that spinal bleeding is found often in young children who are victims of abusive trauma. The findings support performing complete spine imaging for children undergoing brain magnetic resonance imaging (MRI) for moderate or severe traumatic brain injury and suggest a pathway for distinguishing between abusive and accidental injury.

KYTHERA presents long-term results from ATX-101 Phase 2 study at ASDS 2011

KYTHERA Biopharmaceuticals, Inc., a privately-held biotechnology company focused on the development and commercialization of prescription products in aesthetic medicine, presented results from a long-term follow up study assessing persistence of efficacy and post-treatment safety of ATX-101, a first-in-class, injectable drug that is under investigation for the reduction of submental fat.
