New tool tracks brain development in babies
Researchers have used a new technique to monitor brain development in infants and detect disturbances in white matter, according to a study in the July issue of Radiology. view more (2006-06-27)
Mouse model for schizophrenia has genetic on-off switch
Scientists at Johns Hopkins have developed a mouse model for schizophrenia in which a mutated gene linked to schizophrenia can be turned on or off at will. view more (2007-09-11)
Nano-sized technology has super-sized effect on tumors
Anyone facing chemotherapy would welcome an advance promising to dramatically reduce their dose of these often harsh drugs. Using nanotechnology, researchers at Washington University School of Medicine in St. Louis have taken a step closer to that goal. view more (2008-04-03)
MRIs made safe for people with modern defibrillators and pacemakers
Researchers at Johns Hopkins have painstakingly figured out how to safely perform magnetic resonance imaging (MRI) scans on men and women who have any one of 24 modern types of implanted defibrillators and pacemakers. view more (2006-09-19)
PneuStep — MRI-safe motor makes robotic biopsies possible
Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging. view more (2007-04-09)
New hope for severe heart disease patients
Funded by the MBF Foundation, the second phase of the project will test whether using the G-SCF hormone to stimulate the release of blood vessel-forming stem cells can alleviate the condition, improve heart function and increase quality of life for people with severe heart disease. view more (2007-05-31)
New computer program uses brain scans to assess risk of Alzheimer's
New York University School of Medicine researchers have developed a brain scan-based computer program that quickly and accurately measures metabolic activity in a key region of the brain affected in the early stages of Alzheimer's disease. view more (2005-06-20)
MRI analysis could prevent brain damage from stroke, Stanford study finds
A stroke victim arrives in the emergency room and, within minutes, the doctor must make a decision: Should drugs be administered to open up the blocked blood vessel and prevent further brain damage? Or is this patient at high risk for suffering a brain hemorrhage if the blocked vessel is opened? view more (2006-11-02)
Study shows how sleep improves memory
A good night's sleep triggers changes in the brain that help to improve memory, according to a new study led by researchers at Beth Israel Deaconess Medical Center (BIDMC). view more (2005-06-29)
Resemblance between cataplexy during status cataplecticus, normal REM sleep
The first efforts to identify the neural structures and pathways underlying cataplexy during status cataplecticus in a narcoleptic patient, with the use of brain perfusion single photon emission computed tomography (SPECT), have led to the discovery that cataplexy during status cataplecticus, a case of prolonged cataplexy, partially resembles... view more...

Study evaluates brain lesions of older patients
Lesions commonly seen on MRI in the brains of older patients may be a sign of potentially more extensive injury to the brain tissue, according to a recent study conducted by researchers at the Duke University Medical Center, in Durham, NC. view more (2007-07-10)
Polycystic kidney disease: MRI provides an early alert to progression
A new method using magnetic resonance imaging (MRI) accurately tracks structural changes that predict functional changes earlier than standard blood and urine tests in people with autosomal dominant polycystic kidney disease (PKD). view more (2006-05-18)
Cancer drug extends cognitive function in patients with brain metastases
he drug Xcytrin®, based on a molecule developed by chemists at The University of Texas at Austin, shows significant promise in prolonging cognitive function in patients with non-small cell lung cancer that has metastasized to the brain. view more (2006-06-06)
High-tech spectroscopy may be used to monitor neuropsychiatric symptoms
Magnetic resonance spectroscopy (MRS) may provide a noninvasive way to monitor neuropsychiatric symptoms in patients with lupus, according to results from research in mice at Wake Forest University School of Medicine. view more (2006-11-13)
Using nano-magnets to enhance medical imaging
Nanoscale magnets in the form of iron-containing molecules might be used to improve the contrast between healthy and diseased tissue in magnetic resonance imaging (MRI)—as long as the concentration of nanomagnets is carefully managed. view more (2007-02-02)
New technology developed at Barrow Neurological Institute enhances MRI capabilities
Researchers at Barrow Neurological Institute in Phoenix have developed a new method that allows technicians to obtain clearer Magnetic Resonance Imaging (MRI) scans with less sensitivity to patient motion. view more (2006-01-05)
When it comes to intelligence, size matters
A collaborative study led by researchers at the Montreal Neurological Institute (MNI), McGill University has demonstrated a positive link between cognitive ability and cortical thickness in the brains of healthy 6 to 18 year olds. view more (2009-03-26)
HYPER-CEST MRI Breaks New Ground in Molecular Imaging
Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have developed a new technique for Magnetic Resonance Imaging (MRI) that allows detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques. view more (2006-10-23)
Study identifies factors correlated with cerebral palsy
Several factors, including maternal infection during pregnancy, very preterm birth, and certain findings on brain MRI scans were correlated with cerebral palsy. view more (2006-10-04)
Hopkins study describes potentially fatal heart condition among young athletes
A Johns Hopkins study has provided the most comprehensive description to date of people most likely to develop a relatively rare heart condition, called arrhythmogenic right ventricular dysplasia (ARVD), known to be among the top causes of sudden cardiac death among young athletes. view more (2005-12-13)
