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.

Newly-discovered selective process may explain why brain function does not deteriorate

As we grow older, our brains undergo a major reorganisation reducing the connections in the brain. Studying people up to the age of 40, scientists led by Dr Marcus Kaiser and Ms Sol Lim at Newcastle University found that while overall connections in the brain get streamlined, long-distance connections that are crucial for integrating information are preserved.

New MRI approach can be important tool for diagnosing, tracking MS progression

New imaging research from Western University (London, Canada) has demonstrated that a magnetic resonance imaging approach called quantitative susceptibility mapping can be an important tool for diagnosing and tracking the progression of Multiple Sclerosis and other neurological diseases.

Researchers confirm link between contrast agent and abnormalities on brain MRI

For the first time, researchers have confirmed an association between a common magnetic resonance imaging (MRI) contrast agent and abnormalities on brain MRI, according to a new study published online in the journal Radiology. The new study raises the possibility that a toxic component of the contrast agent may remain in the body long after administration.

Researchers identify potential biomarker to predict developmental problems in premature infants

Researchers have identified a potential biomarker for predicting whether a premature infant is at high risk for motor development problems, according to a study published online in the journal Radiology.

Standardized research approaches needed for developing new treatments for neurofibromatosis

As potentially effective new treatments for neurofibromatosis (NF) are developed, standardized research approaches—including outcome measures specific to NF—are needed. The first report from the Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration has been published as a supplement to Neurology, the Official Journal of the American Academy of Neurology (AAN).

New algorithm separates signals into individual frequencies using minimal number of samples

The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing. The algorithm allowed computers to quickly perform Fourier transforms - fundamental operations that separate signals into their individual frequencies - leading to developments in audio and video engineering and digital data compression.

Researchers find decreased energy metabolism in heart cells as significant independent risk factor

Johns Hopkins researchers have identified a new way to predict which heart failure patients are likely to see their condition get worse and which ones have a better prognosis. Their study is one of the first to show that energy metabolism within the heart, measured using a noninvasive magnetic resonance imaging test, is a significant predictor of clinical outcomes, independent of a patient's symptoms or the strength of the heart's ability to pump blood, known as the ejection fraction.

NIST develops prototype calibration tools for experimental medical imaging technique

The National Institute of Standards and Technology (NIST) has developed prototype calibration tools for an experimental medical imaging technique that offers new advantages in diagnosing and monitoring of certain cancers and possibly other medical conditions.

Missing inhibitory connection in brain can trigger social phobias

Fear, at the right level, can increase alertness and protect against dangers. Disproportionate fear, on the other hand, can disrupt the sensory perception, be disabling, reduce happiness and therefore become a danger in itself.

Automated breast density measurement predicts breast cancer risk in younger women

Automated breast density measurement is predictive of breast cancer risk in younger women, and that risk may be related to the rate at which breast density changes in some women as they age, according to research being presented today at the annual meeting of the Radiological Society of North America (RSNA).

Reimbursement cuts for image-guided breast biopsies may reduce women's access to mammography

Drastic reimbursement cuts for image-guided breast biopsies, and other medical imaging techniques in the 2014 Medicare Fee Schedule Final Rule, may further reduce women's access to mammography and other breast cancer services. The Centers for Medicare and Medicaid Services directly cut imaging reimbursement every year since 2007. This, along with 12 Medicare imaging cuts in the last six years due to legislation, increasingly threatens patient care.

MRI provides noninvasive way to measure iron levels in the brains of ADHD people

Magnetic resonance imaging provides a noninvasive way to measure iron levels in the brains of people with attention deficit hyperactivity disorder, according to a study being presented today at the annual meeting of the Radiological Society of North America. Researchers said the method could help physicians and parents make better informed decisions about medication.

Soldiers who suffer blast-induced MTBI exhibit long-term brain differences

Using a special type of magnetic resonance imaging, researchers have found that soldiers who suffered mild traumatic brain injury induced by blast exposure exhibit long-term brain differences, according to a study being presented today at the annual meeting of the Radiological Society of North America.

Study reveals effect of energy drinks on the function of the heart

Healthy adults who consumed energy drinks high in caffeine and taurine had significantly increased heart contraction rates one hour later, according to a study presented today at the annual meeting of the Radiological Society of North America.

Preterm infants at high risk for significant long-term problems

Premature birth appears to trigger developmental processes in the white matter of the brain that could put children at higher risk of problems later in life, according to a study being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

Neurosurgeons use novel technique to visualize the brain's delicate anatomy prior to surgery

Neurosurgeons at UC San Diego Health System are using a new approach to visualize the brain's delicate anatomy prior to surgery. The novel technique allows neurosurgeons to see the brain's nerve connections thus preserving and protecting critical functions such as vision, speech and memory. No needles, dyes or chemicals are needed to create the radiology scan. The main imaging ingredient? Water.

Brain signals in fibromyalgia patients: an interview with Dr. Marco Loggia from Massachusetts General Hospital and Harvard Medical School in Boston

Fibromyalgia patients suffer from a variety of symptoms, including widespread body pain and myofascial tenderness. They are ‘hyperalgesic’, which means that if you give them a stimulus that in healthy subjects is just mildly painful (or even completely innocuous), they may perceive it as excruciatingly painful.
