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 finds usage of advanced radiology in emergency department increases

From 1998 to 2007, the use of CT or MRI scans in emergency departments for injury-related conditions increased about 3-fold without a similar increase in the prevalence of the diagnosis of certain life-threatening trauma-related conditions, according to a study in the October 6 issue of JAMA.

COE on Brain Aging at NYU Langone establishes Lewy Body Disease Center

The Center of Excellence (COE) on Brain Aging at NYU Langone Medical Center has established a specialty center for the diagnosis and treatment of Lewy Body Disease, a multi-system disease involving disturbances of cognition, behavior, sleep and autonomic function. Lewy Body Disease, or LBD, affects an estimated 1.3 million individuals in the United States and is widely misdiagnosed because LBD symptoms closely resemble those of other more commonly known diseases such as Alzheimer's and Parkinson's disease.

Study finds certain MRI sequences as accurate methods of assessing stent stenosis

Researchers have found that magnetic resonance imaging (MRI) may be sufficient for the routine surveillance of some great vessel (primary blood vessels [e.g., aorta and vena cavae]) stents that are commonly used to treat congenital heart defects (a defect in the structure of the heart and great vessels that is present at birth) in children and young adults, according to a study in the October issue of the American Journal of Roentgenology (www.ajronline.org). MRI is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

Warning on Australian clinics offering safe alternatives to mammograms

Experts have warned that some private clinics that are offering safe alternatives to mammograms as breast cancer screening are doing more harm than good. It is seen that clinics offering services like botox, liposuction and spray tans are increasingly providing breast cancer screening that uses thermal imaging and “electrical impedance” technology. These methods are being used on women as young as 20, with claims they can detect cancer years earlier than mammograms.

Blood test developed for non-alcoholic fatty liver disease diagnosis

Scientists at the Basque Center for Cooperative Research in Biosciences (CIC bioGUNE) and OWL Genomics Ltd. (Bilbao, Spain), in collaboration with researchers at the INSERM and University Hospitals (APHP Pitié Salpêtrière Hospital, Pierre & Marie Curie University Paris and Centre Hospitalier Universitaire Nice, University of Nice-Sophia-Antipolis, Nice, France), Vanderbilt University (Nashville, US), the University of Southern California (Los Angeles, US), Clinic Hospital and IDIBAPS (Barcelona, Spain) and the Alcalá de Henares University (Alcalá de Henares, Spain) have used metabolomics technology to develop a blood test for non-alcoholic fatty liver disease (NAFLD) diagnosis.

Researchers to contribute to brain circuit mapping in Human Connectome Project

Thirty-three researchers at nine institutions will contribute to the Human Connectome Project (http://www.humanconnectome.org/consortia). Using powerful, custom-built brain scanners, a supercomputer, new brain analysis techniques and other state-of-the-art resources, they will trace the anatomical 'wires' that interconnect thousands of different regions of the human brain's gray matter.

Bruker launches Icon desktop MRI systems at 2010 World Molecular Imaging Congress

At the 2010 World Molecular Imaging Congress in Kyoto, Bruker Corporation today announces the introduction of the Icon™, a new easy-to-use 1 Tesla desktop MRI scanner that combines simplicity with compact dimensions, in order to bring preclinical magnetic resonance imaging (MRI) within reach for a broader range of molecular imaging laboratories.

MRI recordings at one fiftieth of a second

"Please hold absolutely still": This instruction is crucial for patients being examined by magnetic resonance imaging (MRI). It is the only way to obtain clear images for diagnosis. Up to now, it was therefore almost impossible to image moving organs using MRI. Max Planck researchers from G-ttingen have now succeeded in significantly reducing the time required for recording images - to just one fiftieth of a second.

New non-invasive method to diagnose osteoarthritis

Researchers at New York University have developed an innovative way to look at the development of osteoarthritis in the knee joint-one that relies on the examination of sodium ions in cartilage. Their work, which appears in the Journal of Magnetic Resonance, may provide a non-invasive method to diagnose osteoarthritis in its very early stages.

Noninvasive monitoring of cardiac allograft vasculopathy with fast MR imaging

Cardiac allograft vasculopathy (CAV), also known as chronicle rejection, is a leading cause of graft (foreign heart) loss and death in patients who survive the first year after heart transplantation. The typical pathological change of CAV is gradually thickening of coronary wall in "foreign" heart due to continuous immunological reaction between donated heart and the host. In some cases, undetected CAV may silently cause graft failure with global myocardial ischemia without any documented infarction signs. Thus, continually monitoring development of asymptomatic CAV is important for selecting prophylactic strategies to get better prognosis. However, most current examinations of detecting CAV are invasive and with certain risks.

Magnetic resonance image analysis helps assessment of prostate cancer severity

Rutgers researchers are developing methods that can accurately assess the severity of prostate cancer by analyzing magnetic resonance images and spectra of a patient's prostate gland. This may help physicians decide more confidently which patients need aggressive treatment and which are better served by "watchful waiting," and could even postpone or eliminate invasive biopsies in patients with low-grade tumors.
