GE launches fast, easy-to-use 3T scanner
May 5th 2008GE has unveiled a new 3T scanner, the Signa MR750, the first in a new generation of Signa scanners designed to handle the toughest imaging cases with minimal effort. More powerful gradients, increased anatomical coverage, enhanced parallel imaging, and a user interface that simplifies routine as well as academically challenging protocols promise to allow 3T to reach its clinical potential, said Jim Davis, GE vice president and general manager of global MR business.
ISMRM presentations reflect MR’s varied role in practice and research
May 4th 2008Visitors to the 2008 International Society for Magnetic Resonance in Medicine meeting in Toronto need only wait a minute for the door to swing from clinical issues to advanced research on functional and metabolic imaging.
Added padding: One solution to patient comfort
May 1st 2008A couple of days ago I was in the zone. Shawna’s surgical mask hid her face, but I knew she was smiling. My banter was enough to make her laugh out loud a few times, so much that she paused while laying out the stainless steel instruments that soon would be probing the all too deep pockets between my teeth and gums.
Brain stays cool as jazz man jams
May 1st 2008To the listener, jazz improvisation is an aural flight of fancy, borne aloft by a musician's on-the-spot skill and imagination. But functional MRI results show the brain actually follows a grounded process of activation and deactivation during these spontaneous musical riffs, according to researchers from the National Institutes of Health and Johns Hopkins University.
Brain imaging study uncovers neurophysiology of drunken behavior
April 30th 2008New brain imaging research shows that social drinkers experience decreased sensitivity in brain regions involved in detecting threats and increased activity in regions involved in reward after consuming alcohol. The first human brain imaging study of alcohol’s effect on the response of neuronal circuits to threatening stimuli appears in the April 30 issue of The Journal of Neuroscience.
Brain and spine imaging benefit from increased field strength
April 30th 2008Neuroimaging with MRI at 3T is superior for nearly every application in the brain and spine, and it is certainly inferior for none. The technique has unique strengths for performing vascular work and functional brain imaging, but there is nothing that a 3T MR scanner can't do better than a 1.5T machine.
Report from ARRS: Breast MRI CAD zeroes in on malignancies
April 17th 2008Computer-aided detection schemes for breast MR imaging have shown plenty of promise, but they always fall short of full automation and lesion characterization. Two recent studies, however, suggest CAD for breast MRI may be closing in on true cancer detection.
NSF lawsuit discovery process may expose lax contrast documentation
April 16th 2008A casual attitude toward keeping track of gadolinium-enhanced studies may come back to haunt radiology departments that have become involved in several federal lawsuits alleging a connection between cases of nephrogenic systemic fibrosis and gadolinium-based MR contrast agents.
Scientific abstracts indicate growing prestige of ARRS annual meeting
April 15th 2008What’s happening with the American Roentgen Ray Society? Its annual meeting, known mainly for the quality of its refresher course, has become an essential point of coverage for world-class scientific research as well.
Florida radiologist agrees to pay $7 million to resolve kickback claims
April 15th 2008Dr. Fred L. Steinberg and his imaging centers and related entities in Palm Beach County near Miami will pay $7 million to settle alleged violations of federal Stark self-referral law and anti-kickback statutes. He was also charged with billing fraud.
Report from ARRS: Study establishes infection as NSF risk factor
April 14th 2008New evidence has surfaced pinpointing specific potential causes of nephrogenic systemic fibrosis. Findings sustain its relationship to some gadolinium-based contrast media, but they also suggest that infection, certain patient demographics, and even some drugs could be strongly associated with the condition.
Proton MRS links fibromyalgia pain to changes in brain molecule
April 10th 2008Widespread muscle and tissue pain, tenderness, and fatigue are well-documented symptoms of fibromyalgia, a chronic condition that affects up to an estimated 6% of the U.S. population. The underlying pathology of the pain disease is unknown. A new study featuring proton MR spectroscopy, however, has found a key linkage between the pain and a specific brain molecule.
New recommendations target NSF risk
April 2nd 2008Nephrogenic systemic fibrosis has received widespread attention, but official protocols on how to avoid the life-threatening skin condition are quite sparse: Only one section in the American College of Radiology’s 2007 white paper on safe MR practices is devoted to the condition.
