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.

FDA approves clinical trials to test the safety of cancer-detection technology

The U.S. Food and Drug Administration has approved human clinical trials to test the safety of cancer-detection technology developed at Case Western Reserve University: a tumor-targeting contrast agent that accurately detects aggressive prostate cancer in a magnetic resonance imaging (MRI) scan.

Study measures language-skill improvement by tracking brain activity

A study with first-time learners of Japanese has measured how brain activity changes after just a few months of studying a new language. The results show that acquiring a new language initially boosts brain activity, which then reduces as language skills improve.

Anabolic-androgenic steroids can have deleterious effects on the brain

Anabolic-androgenic steroids (AAS), a synthetic version of the male sex hormone testosterone, are sometimes used as a medical treatment for hormone imbalance. But the vast majority of AAS is used to enhance athletic performance or build muscle because when paired with strength training.

Exercise increases blood flow to the brain, study shows

It's not just your legs and heart that get a workout when you walk briskly; exercise affects your brain as well. A new study by researchers at UT Southwestern shows that when older adults with mild memory loss followed an exercise program for a year, the blood flow to their brains increased.

New algorithm reduces patient wait times, minimizes costs associated with exam delays

The first known study to explore optimal outpatient exam scheduling given the flexibility of inpatient exams has resulted in shorter wait times for magnetic resonance imaging (MRI) patients at Lahey Hospital & Medical Center in Burlington, Mass.

Researchers unveil new technique for observing metabolic processes in real time

Magnetic resonance imaging (MRI) is already widely used in medicine for diagnostic purposes. Hyperpolarized MRI is a more recent development and its research and application potential has yet to be fully explored.

A retinal photo may provide early warning signs of stroke and dementia

Pictures of the retina may someday provide early warning signs that a person is at an increased risk of stroke and dementia, making it possible to take preventive measures, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

New high-performance, safe MRI contrast agent for 3D vascular mapping

Heart attack and stroke are the first and second leading causes of death in developed countries, respectively. As the disease often results in sudden death with few special prognostic symptoms, early diagnosis is very important.

10 Mar 2021

Researchers confirm a threshold value for non-invasive imaging biomarker

Breast cancer is the commonest fatal cancer in women. Early detection increases a woman's chances of recovery. Magnetic Resonance Imaging (MRI) is an accurate technique for detecting and classifying tumors in breast tissue.

FDA permits marketing of new device to protect athletes from harmful effects of head impacts

Today, the U.S. Food and Drug Administration authorized marketing of a new device intended to be worn around the neck of athletes aged 13 years and older during sports activities to aid in the protection of the brain from the effects associated with repetitive sub-concussive head impacts.
