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

Repeated blows to head in contact sports may cause changes in brain's white matter

Repeated blows to the head during a season of contact sports may cause changes in the brain's white matter and affect cognitive abilities even if none of the impacts resulted in a concussion, according to a study published today in the journal Neurology.

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.

Brain network disruption crosses psychosis diagnostic boundaries

Disruption of cortical information processing occurs in patients with psychosis regardless of whether they have a psychotic or affective diagnosis, research shows.

Depression during pregnancy may affect child's mental health

Depression is a serious mental illness that has many negative consequences for sufferers. But depression among pregnant women may also have an impact on their developing babies.

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.

Cognitive behavioral therapy for PTSD affects underlying biology of the disorder

A new paper published in Biological Psychiatry suggests that cognitive behavioral therapy for posttraumatic stress disorder not only reduces symptoms but also affects the underlying biology of this disorder.

New brain connectivity study finds striking differences in the neural wiring of men and women

A new brain connectivity study from Penn Medicine published today in the Proceedings of National Academy of Sciences found striking differences in the neural wiring of men and women that's lending credence to some commonly-held beliefs about their behavior.

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).

Severely neglected children more prone to indiscriminate friendliness

Children who experience profound neglect have been found to be more prone to a behavior known as "indiscriminate friendliness," characterized by an inappropriate willingness to approach adults, including strangers.

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.

Nearly 1% of all newborns in Switzerland diagnosed with congenital heart defect

Approximately one percent of all newborns in Switzerland are diagnosed with a congenital heart defect, roughly half of them require open heart surgery. Most children, including those with the most severe heart defects, survive because of the significant advancements in surgical techniques. Therefore, the current research focuses less on survival than on long-term consequences and quality of life of these children.

Stroke patients report improvements in their motor function using novel rehabilitation device

Using a novel stroke rehabilitation device that converts an individual's thoughts to electrical impulses to move upper extremities, stroke patients reported improvements in their motor function and ability to perform activities of daily living. Results of the study were presented today at the annual meeting of the Radiological Society of North America.

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).
