Diffusion tensor imaging, an MRI technique, showed that significant differences in the brains of high-risk children who go on to develop autism can be seen before symptoms appear.

Diffusion-weighted MRI is the most effective MRI technique to detect and evaluate patient response to platinum-based neoadjuvant chemotherapy for late-state ovarian cancer.

ACR has joined AdMeTech Foundation and the European Society of Urogenital Radiologists to develop standards for the MR Prostate Imaging Reporting and Data System.

Using magnetization transfer ratio (MTR) researchers found a reduction in contrast enhancing lesions, possibly inducing remyelination.

Steven Kalkanis, MD, director of neurosurgical oncology at Henry Ford West Bloomfield Hospital, discusses how an MRI unit in the operating suite has transformed their approach to brain surgery.

Pamela Woodard, MD, of the Mallinckrodt Institute of Radiology at Washington University School of Medicine in St. Louis, discusses the challenges and benefits of being an early adopter of this technology.

A new magnetic resonance spectroscopy technique provides a definitive diagnosis of brain cancer based on imaging of a protein associated with a mutated gene.

Preoperative MRI helps surgeons make better decisions about nerve-sparing procedures in men with prostate cancer, according to a study in the journal Radiology.

Researchers at Brigham and Women’s Hospital and Tel Aviv University have built a tiny pill camera that would be powered and maneuvered by MRI.

Magnetic resonance imaging can help quantify the loss of gray matter in childhood-onset schizophrenia, bipolar disorder and other psychoses, possibly helping diagnose the cases to become more serious.

Cardiovascular MRI beats SPECT in diagnosing heart disease, according to the authors of a major British study published online on Dec. 23 in The Lancet.

University of Pennsylvania researchers have developed an experimental MRI contrast agent capable of targeting tumors, according to a report in the journal ACS Nano. Its coating, instead of targeting particular cancer receptors - which can be hit-or-miss and depend on the cancer - is attracted to the acidic environments in which tumors generally thrive.

Magnetic resonance imaging does not appear to help patients slated for epidural steroid injections (ESI) for chronic lower back pain, and has only a minor effect on the physician’s decision making, according to a study published online this week by the Archives of Internal Medicine.

A far quicker MRI scan is on the horizon. A new algorithm developed by MIT’s Research Laboratory of Electronics cuts the imaging time by two-thirds, though they’re still working on the back end processing time. Authors of the research, which is scheduled for publication in the journal Magnetic Resonance in Medicine, say that a 45-minute scan can be done in 15 minutes without compromising much of the quality.

Researchers just found what they said is a cheaper and safer way to diagnose and track Alzheimer’s disease, using arterial spin labeling (ASL), a magnetic resonance imaging (MRI) technique. University of Pennsylvania’s Perelman School of Medicine researchers published twice on the technique this month.

CHICAGO - Ninety-seven percent of U.S. teens play games either on the computer, Web or console. Of adolescent boys, 50 percent admit to playing video games rated Mature. These statistics are perhaps far more startling after a study presented Wednesday at RSNA that showed violent video games alter brain function in young men.

Magnetization transfer (MT) contrast-prepared magnetic resonance imaging is “unlikely to be of clinical utility” in diagnosing cirrhosis, according to a study published online Nov. 23 in the journal Radiology.

MRI shows little evidence of benefiting breast-cancer treatment, according to the first paper in The Lancet’s new series on breast cancer.

An early treatment MRI can predict a multiple sclerosis (MS) patient’s five-year disability progression, according to a study recently presented in the Netherlands. The study found that by performing an MRI six to 12 months after treatment initiation, it’s possible to predict whether a patient will respond to the given treatment long term.

Inhaling undiluted, hyperpolarized xenon 129 for magnetic resonance imaging of the lungs is safe for chronic obstructive pulmonary disease (COPD) patients as well as healthy volunteers, Duke University researchers reported online on Nov. 4 in the journal Radiology.

MRI measurements of inflammatory precursors to rheumatoid arthritis are central to the early application of a promising anti-arthritis therapy, according to a study published in the British Medical Journal.

The FDA is holding a forum this month to address MRI safety concerns and find ways to cut incidents. Industry leaders agree there should be safety standards in place, but are mixed on whether federal regulation is needed. What do you think?

Diffusion-weighted MRI patterns can guide the work-up for patients presenting with acute ischemic stroke symptoms, according to a study in the November Journal of Neurology, Neurosurgery & Psychiatry.

MRI-related accidents and injury reporting are on the rise, prompting the FDA to examine thermal burns, projectiles, implantable devices, and hearing loss.

The Discovery MR750w with Geometry Enhancing Method (GEM) suite of coils has a patient-friendly design and 70 cm bore to accommodate the hard-to-scan patients, such as larger, claustrophobic, elderly or very young patients, the company said.

The largest-ever study on the effects of magnetic resonance imaging on pacemakers and defilibrators has concluded that the imagers are indeed safe for those with these cardiac rhythm management devices.

Plaque rupture and ulceration is common in women who suffer heart attacks, but whose angiographs show no coronary artery disease, according to a study published online in the journal Circulation.
