April 30, 2008 Demand for MR scanners slumps in 2007 Greg Freiherr -------------------------------------------------------------------------------- Despite expanding clinical applications driven by functional and breast imaging, MR scanners are stuck in a sales doldrums. Vendors last year sold about 850 new units to customers in the U.S., about 7% less than the year before. Their sale produced $1.3 billion in revenue, about 4% less than in 2006. Sales turned up in the fourth quarter last year,…

April 29, 2008 Intensity-modulated breast therapy approach reduces radiation-induced dermatitis Shalmali Pal -------------------------------------------------------------------------------- Preventing adverse skin reactions during breast radiotherapy is a challenge. Attempts to address the problem with topical creams or hygiene have been unsuccessful. Instead, Canadian researchers have gone back to the source of the problem and found that using intensity-modulated radiation therapy can reduce…
