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

TAU researcher develops capsule endoscope to investigate digestive system

Endoscopes - small cameras or optic fibres that are usually attached to flexible tubing designed to investigate the interior of the body - can be dangerously invasive. Procedures often require sedative medications and some recovery time. Now a researcher at Tel Aviv University is developing a "capsule endoscope" that can move through the digestive tract to detect problems independent of any attachments.

Decision support tool for objective diagnostics of Alzheimer's

European PredictAD project, lead by Principal Scientist Jyrki Lötjönen from VTT Technical Research Centre of Finland, has developed a decision support tool for objective diagnostics of Alzheimer's disease.

MRI can predict breast cancer prognosis

Quantitative magnetic resonance imaging measures were associated with prognostic tumor markers, demonstrating the potential of magnetic resonance imaging for prediction of disease prognosis and stratification of patients to appropriate therapies, according to preliminary data presented at the 2011 CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 6-10, 2011.

HCI earns NCI's Center for Quantitative Imaging Excellence certification

Precise, accurate imaging—think mammography, CT and MRI scans—is important to cancer screening, treatment, and follow-up care. Now, even more advanced technology is emerging, and with it, the need for imaging specialists with the expertise to use them.

Autism linked with disorganized structure of brain's white matter

It's still unclear what's different in the brains of people with autism spectrum disorders (ASDs), but evidence from genetic and cell studies points to abnormalities in how brain cells (neurons) connect to each other. A study at Children's Hospital Boston now provides visual evidence associating autism with a disorganized structure of brain connections, as well as defects in myelin -- the fatty, insulating coating that helps nerve fibers conduct signals and that makes up the brain's white matter.

The head plays key role in tiring endurance performances

Researchers from the University of Zurich have now studied in detail what sportsmen and women know from experience: The head plays a key role in tiring endurance performances.

Study reveals how wide brain networks are activated during music listening

Finnish researchers have developed a groundbreaking new method that allows to study how the brain processes different aspects of music, such as rhythm, tonality and timbre (sound color) in a realistic listening situation.

Evaluating passive harms requires more thought, finds study

People typically say they are invoking an ethical principle when they judge acts that cause harm more harshly than willful inaction that allows that same harm to occur. That difference is even codified in criminal law.

Yale researchers monitor growth of laboratory-engineered blood vessels after implantation

Using magnetic resonance imaging (MRI) and nanoparticle technology, researchers from Yale have devised a way to monitor the growth of laboratory-engineered blood vessels after they have been implanted in patients. This advance represents an important step toward ensuring that blood vessels, and possibly other tissues engineered from a patient's own biological material, are taking hold and working as expected.

New review article: Pitch center does not exist in auditory cortex

The perceptual feature of sound known as pitch is fundamental to human hearing, allowing us to enjoy the melodies and harmonies of music and recognize the inflection of speech. Previous studies have suggested that a particular hotspot in the brain might be responsible for perceiving pitch. However, auditory neuroscientists are still hotly debating whether this "pitch center" actually exists.

Study finds structure-function impairments in people addicted to cocaine

The more gray matter you have in the decision-making, thought-processing part of your brain, the better your ability to evaluate rewards and consequences. That may seem like an obvious conclusion, but a new study conducted at the U.S. Department of Energy's Brookhaven National Laboratory is the first to show this link between structure and function in healthy people - and the impairment of both structure and function in people addicted to cocaine.

Phillips gets FDA approval for its combo PET/MRI scanner

Royal Philips Electronics NV has received approval from U.S. regulators to introduce a single medical imaging device that can scan the body for cancer using two technologies.

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).

Sensorimotor experience influences brain’s linking of signals from different senses

Over the years pianists develop a particularly acute sense of the temporal correlation between the movements of the piano keys and the sound of the notes played. However, they are no better than non-musicians at assessing the synchronicity of lip movements and speech.

Violent video game play has a long-term effect on brain functioning

A functional magnetic resonance imaging (fMRI) analysis of long-term effects of violent video game play on the brain has found changes in brain regions associated with cognitive function and emotional control in young adult men after one week of game play.

Potential biomarkers for ADHD

Using functional magnetic resonance imaging (fMRI), researchers have identified abnormalities in the brains of children with attention deficit/hyperactivity disorder (ADHD) that may serve as a biomarker for the disorder, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

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.
