NIH study finds MRI more sensitive than CT in diagnosing most common form of acute stroke
Results from the most comprehensive study to compare two imaging techniques for the emergency diagnosis of suspected acute stroke show that magnetic resonance imaging (MRI) can provide a more sensitive diagnosis than computed tomography (CT) for acute ischemic stroke. The difference between MRI and CT was attributable to MRI's superiority for detection of acute ischemic strokethe most common fo...HYPER-CEST MRI breaks new ground in molecular imaging
BERKELEY, CA -- 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. Called HYPER-CEST, for hyperpolarized x...Draft environmental impact statement prepared for USAMRIID facilities at Fort Detrick
The Department of the Army has issued a Notice of Availability of a Draft Environmental Impact Statement (DEIS) associated with the construction and operation of new U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) facilities and the decommissioning and demolition or re-use of the existing USAMRIID facilities at Fort Detrick, Maryland. A Public Meeting for the DEIS will b...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), according to a study funded by the National Institutes of Health (NIH). PKD is a common inherited condition characterized by cysts that grossly distort the kidneys an...MRI study opens door to assessing, preventing dangerous brain iron levels
A magnetic resonance imaging (MRI) study at UCLA opens new doors to assessing and potentially preventing brain iron accumulation associated with risk of developing degenerative brain diseases such as Alzheimer's, Parkinson's and Dementia With Lewy Bodies. ......Posted as an early online publication of the peer-reviewed journal Neurobiology of Aging, this largest-ever study of brain iron demonstra...MRI drug may improve cancer-killing ability of chemotherapy, study says
A contrast agent currently used in magnetic resonance imaging (MRI), called mangafodipir, may increase the cancer-killing ability of some chemotherapy drugs while protecting normal cells, according to a study in the February 15 issue of the . ... ...Many anticancer drugs work by increasing the levels of tumor cell hydrogen peroxide. Tumor cells are particularly sensitive to hydrogen peroxide and...Environmental impact statement planned for USAMRIID facilities at Fort Detrick
The Department of the Army issued today a Notice of Intent to prepare an Environmental Impact Statement (EIS) associated with the construction and operation of new U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) facilities and the decommissioning and demolition or re-use of the existing USAMRIID facilities at Fort Detrick, Maryland. A Public Scoping Meeting will be conduc...Researchers know what you were about to say; fMRI used to detect memory storage and retrieval
Using functional magnetic resonance imaging, or fMRI, researchers at the University of Pennsylvania and Princeton University have provided evidence that the act of recalling a memory is a bit like mental time travel. Their study, presented in the Dec. 23 edition of the journal Science, demonstrates that the same areas of the brain that are active during an event are activated when a person attem...MRI best tool for studying intricate nerves in dogs
Nov. 22, 2005 - A recent study in the journal Veterinary Radiology and Ultrasound presents the first description of the anatomy of a dog's cranial nerves (CN), a once difficult procedure now made possible by using magnetic resonance imaging (MRI) as a diagnostic modality....... "By knowing the normal MRI anatomy of cranial nerve emergences in the dog, the clinician will better recognize lesions a...Insight into cell metabolism will help interpret PETs, MRIs
ITHACA, N.Y. -- By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) t...Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive
BETHESDA, Md. (May 31, 2005) You just can't tell where you might find love these days. A team led by a neuroscientist, an anthropologist and a social psychologist found love-related neurophysiological systems inside a magnetic resonance imaging machine. They detected quantifiable love responses in the brains of 17 young men and women who each described themselves as being newly and madly in love...Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals
PITTSBURGH--In a first, Carnegie Mellon University scientists have "programmed" cells to make their own contrast agents, enabling unprecedented high-resolution, deep-tissue imaging of gene expression. The results, appearing in the April issue of Nature Medicine, hold considerable promise for conducting preclinical studies in the emerging field of molecular therapeutics and for monitoring the deli...Incubator company at NJIT develops lifesaving MRI coil for small animals
NEWARK, Mar 7-Supertron, a start-up technology company housed in the small business incubators at New Jersey Institute of Technology (NJIT, announced today that it has begun developing a cryogenic coil to improve Magnetic Resonance Imaging (MRI) scanners. ... "The new coil will be well suited for animal imaging," said Supertron President Jon T. DeVries. "Small animal models, particularly gene...PET/MRI scans may help unravel mechanisms of prenatal drug damage
RESTON, Va.--Scientists have demonstrated a new way to assess the potentially damaging effects of prenatal drug exposure--a technique that could also be used to monitor a fetus's response to therapeutic drugs--using sophisticated, noninvasive medical imaging tools. Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, whose findings are reported in the February issue of th...MRI 'excellent choice' for overcoming challenges of diagnosing pregnant women with abdominal pain
MRI is both safe and accurate for diagnosing pregnant women with acute pain in the abdomen and pelvis, surpassing the limits of both CT and ultrasound for this purpose, according to a new study by researchers from University of North Carolina Hospitals in Chapel Hill, NC.... ...For the study, the researchers analyzed the MR images of 29 pregnant patients who had been experiencing acute abdominal...
