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.

Study of Gulf War veterans finds link between poor sleep quality and reduced gray matter

A new study of Gulf War veterans found an association between poor sleep quality and reduced gray matter volume in the brain's frontal lobe, which helps control important processes such as working memory and executive function.

Scripps Green Hospital first to implant world's smallest implantable cardiac monitoring device

Scripps Green Hospital has become the first hospital in the United States to implant the world's smallest implantable cardiac monitoring device. Scripps Clinic cardiologist John Rogers, M.D., successfully completed the first implant of the Reveal LINQ- Insertable Cardiac Monitor (ICM) in 71-year-old San Diego resident Chuck Beal on Saturday.

Neurosurgeons use MRI-guided laser technology to treat deep brain tumor

Using a novel magnetic resonance imaging (MRI)-guided laser technology, neurosurgeons at UC San Diego Health System have successfully treated a malignant tumor deep inside a patient's brain. This is the first time that this FDA-approved laser-based treatment has been performed in California.

New research shows that saturated fat builds more fat, less muscle than polyunsaturated fat

New research from Uppsala University shows that saturated fat builds more fat and less muscle than polyunsaturated fat. This is the first study on humans to show that the fat composition of food not only influences cholesterol levels in the blood and the risk of cardiovascular disease but also determines where the fat will be stored in the body.

iASSIST device improves surgical precision, accuracy in total knee replacements

Each year, approximately 600,000 total knee replacement procedures are performed in the United States, a number that is expected to rise exponentially in the next decade as the population ages. Successful surgeries require precise alignment in the knee, a challenging task made even more daunting by the expected rise in procedures. To help meet this demand, UC San Diego Health System is the first in the nation to use iASSIST, a computer navigation system with Bluetooth-like technology that improves surgical precision and accuracy in total knee replacements, decreasing the need for revision surgery.

New radiation-free MRI test effectively diagnoses cancer in children

A new type of whole-body magnetic resonance imaging test could be an alternative to standard positron emission tomography/computed tomography imaging for assessing cancer in children and young adults, but without exposure to radiation that has been shown to increase the risk of secondary cancers in later life.

Researchers develop catheter-based device that provides 3-D imaging from inside heart, blood vessels

Researchers have developed the technology for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart, coronary arteries and peripheral blood vessels. With its volumetric imaging, the new device could better guide surgeons working in the heart, and potentially allow more of patients' clogged arteries to be cleared without major surgery.

Being overweight may cause changes in brain that is crucial to appetite, emotions and memory

Being overweight appears related to reduced levels of a molecule that reflects brain cell health in the hippocampus, a part of the brain involved in memory, learning, and emotions, and likely also involved in appetite control, according to a study performed by researchers at SUNY Downstate Medical Center and other institutions.

New combination MRI-ultrasound imaging system improves treatment for prostate cancer patients

A new combination MRI-ultrasound imaging system can result in fewer biopsies and better treatment decisions for prostate cancer patients.

New research aims for better monitoring, treatment for chronic kidney disease

Detailed structural and functional 'maps' of the human kidney made using advanced scanning technology are to be developed by scientists at The University of Nottingham.

Researchers develop multifunctional nanoparticle to pinpoint blood vessel plaques

A team of researchers, led by scientists at Case Western Reserve University, has developed a multifunctional nanoparticle that enables magnetic resonance imaging (MRI) to pinpoint blood vessel plaques caused by atherosclerosis.

New study correlates brain activity with how people make decisions when they engage in risky behavior

A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it's probably not because their brains' desire systems are too active, but because their self-control systems are not active enough.

Scientists use SWI to study changes in brains of college-level ice hockey players with concussion

Using susceptibility-weighted imaging (SWI), researchers have identified microstructural changes in the brains of male and female college-level ice hockey players that could be due to concussive or subconcussive trauma.

UNC researchers develop new radiation-free ultrasound technique to detect, monitor cancer

While ultrasound provides a less expensive and radiation-free alternative to detecting and monitoring cancer compared to technologies such as X-rays, CT scans, and MRIs, ultrasound has seen limited use in cancer treatment due to clarity and resolution issues.

Aspirin intake correlates with halted growth of lethal intracranial tumor

Researchers from Massachusetts Eye and Ear, Harvard Medical School, Massachusetts Institute of Technology and Massachusetts General Hospital have demonstrated, for the first time, that aspirin intake correlates with halted growth of vestibular schwannomas (also known as acoustic neuromas), a sometimes lethal intracranial tumor that typically causes hearing loss and tinnitus.

Collaboration between NFL and GE seeks to improve safety of athletes, soldiers who sustain mild TBI

When the Broncos and the Seahawks meet on the gridiron for Superbowl XLVIII, player and team statistics - passer ratings, rushing yards, sacks and fumbles - will be tossed around like, well, a football.

Research reveals why people lose hearing as they become old

Although the brain becomes smaller with age, the shrinkage seems to be fast-tracked in older adults with hearing loss, according to the results of a study by researchers from Johns Hopkins and the National Institute on Aging. The findings add to a growing list of health consequences associated with hearing loss, including increased risk of dementia, falls, hospitalizations, and diminished physical and mental health overall.

People who suffer from brain injuries, strokes often have problems paying attention, concentrating

The brain appears to synchronize the activity of different brain regions to make it possible for a person to pay attention or concentrate on a task, scientists at Washington University School of Medicine in St. Louis have learned.

MRI method to map creatine in heart may help detect disorders earlier than traditional methods

A new MRI method to map creatine at higher resolutions in the heart may help clinicians and scientists find abnormalities and disorders earlier than traditional diagnostic methods, researchers at the Perelman School of Medicine at the University of Pennsylvania suggest in a new study published online today in Nature Medicine.
