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.

Magnetized molecules help monitor breast cancer

A study published in the journal Proceedings of the National Academy of Sciences reports on a novel type of scanning which uses magnetized molecules to visualize active areas within a breast tumor specifically. This marks the first successful attempt to demonstrate the role of this type of scanning in the field of breast cancer monitoring.

Maternal stress affects fetal brain development

A new study published online January 13, 2020, in the journal JAMA Pediatrics reports that mothers who suffer severe mental stress during pregnancy may have babies with abnormal development in important areas of the brain even before birth. It is already known that babies with congenital heart disease show abnormalities in brain growth and brain biochemical reactions.

Losing Tongue Fat Improves Sleep Apnea

Doctors already know that weight loss can be an effective treatment for improving sleep apnea, although the reasons for this have remained unclear. Now, new research has uncovered that a reduction in tongue fat is the key to why fat loss helps in instances of Obstructive Sleep Apnea (OSA).

New method uses MRI, machine learning to forecast genetic mutations in glioma tumors

Researchers at Osaka University have developed a computer method that uses magnetic resonance imaging (MRI) and machine learning to rapidly forecast genetic mutations in glioma tumors, which occur in the brain or spine. The work may help glioma patients to receive more suitable treatment faster, giving better outcomes.

Penn researchers use MRI scans to predict 10-year breast cancer recurrence

Diverse diseases like breast cancer can present challenges for clinicians, specifically on a cellular level. While one patient's tumor may differ from another's, the cells within the tumor of a single patient can also vary greatly.

Understanding brain areas responsible for perception of touch

An encouraging pat on the back or a soft sweater on the skin - even things that we do not actively explore with the hands, we perceive with our body perception. "Which brain areas are responsible for this perception of touch, however, is still largely unknown," says Privatdozent Dr. Burkhard Pleger, neurologist at the Berufsgenossenschaftlichen Kliniken Bergmannsheil in Bochum and co-author of the study.

Obese teenagers at risk for brain damage, suggests new study

A new study being presented at the yearly conference of the Radiological Society of North America (RSNA) reports that MRI scanning of the brain shows signs of brain damage in obese adolescents – and that these signs could be the result of brain inflammation.

Dreams can help us react better to frightening situations

Do bad dreams serve a real purpose? To answer this question, researchers from the University of Geneva and University Hospitals of Geneva, Switzerland, - working in collaboration with the University of Wisconsin (USA) - analyzed the dreams of a number of people and identified which areas of the brain were activated when they experienced fear in their dreams.
