Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.

Virtual childbirth software can help plan majority of C-sections

Newly developed computer software combined with magnetic resonance imaging (MRI) of a fetus may help physicians better assess a woman's potential for a difficult childbirth. Results of a study using the new software were presented today at the annual meeting of the Radiological Society of North America (RSNA).

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.

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.

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.

Ocrelizumab drug holds promise for multiple sclerosis

An experimental drug called Ocrelizumab has shown promise in a Phase 2 clinical trial involving 220 people with multiple sclerosis (MS), an often debilitating, chronic autoimmune disease that affects an increasing number of people in North America.

MIT develops new software to speed up MRI scans

Magnetic resonance imaging (MRI) devices can scan the inside of the body in intricate detail, allowing clinicians to spot even the earliest signs of cancer or other abnormalities. But they can be a long and uncomfortable experience for patients, requiring them to lie still in the machine for up to 45 minutes.

Abbott, Biogen Idec announce additional results from daclizumab HYP Phase 2b trial for RRMS

Today Biogen Idec and Abbott announced additional results from the SELECT Phase 2b trial, the first of two registrational studies designed to evaluate the investigational compound daclizumab high-yield process in people with relapsing-remitting multiple sclerosis.

MRI helps researchers to study molecules directly in organs and tissue

Researchers at Lund University can now study molecules which are normally only found in very small concentrations, directly in organs and tissue. After several years of work, researchers in Lund have managed to construct an instrument that 'hyperpolarises' the molecules and thus makes it possible to track them using MRI.

Combination of available medical tests helps identify risk of AD

With age, forgetfulness and other signs of memory loss sometimes appear, prompting elderly individuals to seek a medical evaluation amid fears that they may be experiencing early symptoms of Alzheimer's disease (AD), the most common type of dementia among Americans aged 65 and older.

NIST, CU develop novel low-power transport microchip

Researchers from the National Institute of Standards and Technology (NIST) and University of Colorado Boulder (CU) have developed a low-power microchip that uses a combination of microfluidics and magnetic switches to trap and transport magnetic beads. The novel transport chip may have applications in biotechnology and medical diagnostics.

Young adults born prematurely show multiple biological signs of risks to future health

Young adults who were born prematurely show multiple biological signs of risks to future health, research from Imperial College London has found. The scientists, reporting their findings tomorrow in the journal Pediatric Research, say that the research indicates that urgent work is now needed to monitor preterm babies into adulthood to improve the detection of early signs of disease.

AiC: Health Research receives U.S. Army grant for neuroimaging studies of human performance

The Arlington Innovation Center: Health Research (AiC: Health Research), of Virginia Tech's National Capital Region, has been awarded a $1.5 million cooperative research and development agreement from the U.S. Army for neuroimaging studies of human performance.

Our brain may filter out negativity to provide a rosier picture: Study

A new study shows that a reason why optimists retain a positive outlook even in the face of reality could be that the brain rejects bad news. The study published in Nature Neuroscience adds that in some people, anything negative is practically ignored - with them retaining a positive world view.

NICU stress linked with alterations in brain structure and function of preterm infants

New research shows that exposure to stressors in the Neonatal Intensive Care Unit (NICU) is associated with alterations in the brain structure and function of very preterm infants. According to the study now available in Annals of Neurology, a journal published by Wiley-Blackwell on behalf of the American Neurological Association and Child Neurology Society, infants who experienced early exposure to stress displayed decreased brain size, functional connectivity, and abnormal motor behavior.
