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.

Stress fracture: Causes and treatment strategies

When pain from increased physical activity doesn’t go away in a couple of days, the cause could be a stress fracture. The March issue of Mayo Clinic Health Letter covers these tiny, partial bone fractures, why they occur and how they are treated.

New clinical guidelines: Early diagnosis and treatment of TAD can save lives

When actor John Ritter died suddenly in 2003 from a tear in his thoracic aorta-the large artery that carries blood from the heart to the rest of the body-that tragedy brought attention to a rare but deadly condition that takes the lives of an estimated 10,000 Americans each year.

Cryotherapy offers potential treatment options for breast cancer patients

Interventional radiologists have opened the door to an encouraging potential future treatment for the nearly 200,000 women who are diagnosed with breast cancer in the United States each year: image-guided, multiprobe cryotherapy.

Uterine fibroids: Promising new minimally invasive treatment using high-energy ultrasound waves

There's a new interventional radiology tool showing promise in the treatment of uterine fibroids: magnetic resonance-guided focused ultrasound (MRgFUS), a minimally invasive treatment that uses high-energy ultrasound waves to generate heat at a specific point to destroy uterine fibroid tissue and relieve symptoms.

Flu infection during pregnancy may increase risk of schizophrenia in offspring

Rhesus monkey babies born to mothers who had the flu while pregnant had smaller brains and showed other brain changes similar to those observed in human patients with schizophrenia, a study at the University of Wisconsin-Madison in collaboration with the University of North Carolina at Chapel Hill has found.

MIT researchers to use Elekta Neuromag system to study neural basis of brain disorders

Researchers at MIT are eagerly anticipating the summer delivery of Elekta Neuromag®, a system that uses magnetoencephalography or MEG to explore brain function. MEG can detect the very weak magnetic fields arising from electrical activity in the brain, and allows researchers to monitor the timing of brain activity with millisecond precision.

PINC trial to test anti-malarial drug in women with DCIS

Can a drug that has been used to treat malaria for years possibly be used to treat breast cancer before it becomes invasive? That's what researchers at George Mason University's Center for Applied Proteomics and Molecular Medicine (CAPMM) and Inova Breast Care Institute (IBCI) are trying to prove.

Robotic surgery does not compromise clinical outcomes for prostate cancer surgery

Robotic surgical technology with its three-dimensional, high-definition view gives surgeons the sensation of touch, even as they operate from a remote console. A new study describes the phenomenon, called intersensory integration, and reports that surgical outcomes for prostate cancer surgery using minimally invasive robotic technology compare favorably with traditional invasive surgery.

$Visceral fat can increase fracture risk in obese teenage girls$

Visceral fat can increase fracture risk in obese teenage girls

According to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM), obese teenage girls with a greater ratio of visceral fat (fat around internal organs) to subcutaneous fat (fat found just beneath the skin) are likely to have lower bone density than peers with a lower ratio of visceral to subcutaneous fat.

Outpatient referrals from primary care physicians for CT, MRI studies inappropriate: Academic medical center

A large academic medical center has found that a significant percentage of outpatient referrals they receive from primary care physicians for computed tomography (CT) and magnetic resonance imaging (MRI) studies are inappropriate (based upon evidence-based appropriateness criteria developed by a radiology benefits management company), according to a study in the March issue of the Journal of the American College of Radiology (www.jacr.org).

Growth rate among non-radiologists who own/lease PET equipment is on the rise: Study

Just as with computed tomography (CT) and magnetic resonance imaging (MRI), the growth rate among non-radiologists who own or lease positron emission tomography (PET) equipment is also on the rise, contributing significantly to the ongoing issues surrounding self-referral and unnecessary utilization of imaging in the United States, according to a study published in the March issue of the Journal of the American College of Radiology (www.jacr.org)

EVA trial: MRI is more accurate for early diagnosis of breast cancer than digital mammography

Do we need a revision of current recommendations for breast cancer screening? According to a recent prospective multicenter cohort study published in the "Journal of Clinical Oncology", this appears advisable at least for young women carrying an increased risk of breast cancer. The results of the EVA trial confirm once more that magnetic resonance imaging (MRI) is substantially more accurate for early diagnosis of breast cancer than digital mammography or breast ultrasound: MRI is three times more sensitive for breast cancer than digital mammography.

New research using MRI shows that childhood stress can lead to structural brain changes

New research using magnetic resonance imaging (MRI) shows that childhood stress such as abuse or emotional neglect, in particular when combined with genetic factors, can result in structural brain changes, rendering these people more vulnerable to developing depression. The study led by scientists at Trinity College Dublin has just been published in the international scientific journal, Neuropsychopharmacology.
