Radisphere skirts local groups in bid for hospital contracts
April 15, 2010 -- That sound you hear might just be a dam breaking. Radiology's traditional model of community-based group practices suffered another blow last week with the launch of Radisphere National Radiology Group, which is bypassing local radiology practices to sign contracts directly with hospitals.
Automated exposure control delivers uneven CT dose reduction
April 15, 2010 -- Reducing tube current may be a popular way to lower CT radiation dose, but it's not necessarily an effective one. In a new study, medical physicists from Greece found that organ dose reductions resulting from tube current modulation with automated exposure control can vary -- especially in children.
MR scans may detect signs of early dementia in elderly
April 14, 2010 -- TORONTO - MRI can detect signs of white-matter hyperintensity in the elderly that may indicate three times the risk of developing dementia, according to a French study presented this week at the American Academy of Neurology's annual meeting.
CT shows abdominal fat is unreliable Crohn's treatment target
April 14, 2010 -- A few reports have associated abdominal visceral fat with more aggressive forms of Crohn's disease, but the strength of the association -- and the implications for treatment -- remain unclear. Researchers from Ireland decided to try CT to resolve the issue.
CT delivers 91% of total pediatric ER radiation dose
April 14, 2010 -- MDCT may be used half as often as general radiography for examining children in the pediatric trauma center at Johns Hopkins University, but the modality is responsible for 91% of the ionizing radiation exposure associated with diagnosing their injuries.
Computer analysis bolsters liver elastography performance
April 14, 2010 -- Computer-enhanced dynamic analysis of ultrasound elastography movies is a useful and reliable method for depicting liver hardness, yielding a high level of interreader agreement, according to research published April 14 in the World Journal of Gastroenterology.
VA saved billions with enterprise HIT investment
April 13, 2010 -- The U.S. Department of Veterans Affairs' (VA) initiative to implement healthcare IT more than 20 years ago has paid off impressively. By 2007, the agency had saved a cumulative $3.09 billion, and it's currently saving nearly $700 million annually, according to a study published in the April issue of Health Affairs.
MR pulmonary angio should be limited to expert sites
April 13, 2010 -- Researchers from seven hospitals have concluded that MR pulmonary angiography should be considered only at centers that routinely perform the procedure well, and it should be done only for patients for whom standard tests are contraindicated.
The Profit Center: Part 13 -- Radiology as factory work?
April 13, 2010 -- Are radiologists succumbing to a factory-worker mentality? Such thinking is dangerous, according to healthcare business and legal affairs expert Mark Weiss. In this edition of the Profit Center, he offers ways for radiologists to change this mentality and move from being treated as a commodity to being treated as a unique resource.
