Steroids help reverse rapid bone loss tied to rib fractures
Feb. 5, 2013 New research in animals triggered by a combination of serendipity and counterintuitive thinking could point the way to treating fractures caused by rapid bone loss in people, including patients with metastatic cancers. A series of studies at the University of North Carolina School of Medicine found that steroid drugs, known for inducing bone loss with prolonged use, actually help suppress a molecule that’s key to the rapid bone loss process.
Novel radiation therapy method shortens prostate cancer treatment time
Feb. 1, 2013 According to a study in the January issue of the Journal of the American College of Radiology , the use of volume-modulated arc therapy (VMAT) to deliver intensity-modulated radiation therapy (IMRT) to prostate cancer patients results in an overall reduction in treatment time of approximately 14 percent
Needless abdominal CT scans can be avoided in children, study says
Feb. 1, 2013 A study of more than 12,000 children from emergency departments throughout the country in the Pediatric Emergency Care Applied Research Network (PECARN) has identified seven factors that can help physicians determine the need for a computed tomography (CT) scan following blunt trauma to the abdomen.
Transparent pricing doesn’t curb doctors’ use of high-cost hospital imaging tests
Jan. 23, 2013 In a study designed to see if doctors who are told the exact price of expensive medical tests like MRIs in advance would order fewer of them, Johns Hopkins researchers got their answer: No. In a report published online in the Journal of the American College of Radiology , the researchers found that revealing the costs of MRIs and other imaging tests up front had no impact on the number of tests doctors ordered for their hospitalized patients
Outsourced radiologists perform better reading for fewer hospitals
Jan. 4, 2013 Experience working for a particular hospital matters when it comes to the performance of radiologists who work for outsourcing teleradiology companies, according to a team of researchers, whose finding could have important implications, given the growing use of telemedicine. “More than half of all hospitals now use teleradiology services,” said Jonathan Clark, assistant professor of health policy and administration, Penn State
Plvap/PV1 critical to formation of the diaphragms in endothelial cells
Jan. 3, 2013 Dartmouth scientists have demonstrated the importance of the gene Plvap and the structures it forms in mammalian physiology in a study published in December by the journal Developmental Cell
Second impact syndrome in a high school football player: Researchers use imaging findings to chronicle new details
Jan. 1, 2013 In the January 2013 issue of the Journal of Neurosurgery: Pediatrics , physicians at the Indiana University School of Medicine and the Northwest Radiology Network (Indianapolis) report on the case of a 17-year-old high school football player with second impact syndrome (SIS). A rare and devastating traumatic brain injury, SIS occurs when a person — most often a teenager — sustains a second head injury before recovery from an earlier head injury is complete.
Paired CT scans catch chemo-killing of liver tumors in real time
Dec. 31, 2012 Using two successive pairs of specialized CT scans, a team of Johns Hopkins and Dutch radiologists has produced real-time images of liver tumors dying from direct injection of anticancer drugs into the tumors and their surrounding blood vessels
