Health & Wellness NewsNovember 20, 2009 | Taking menstrual cycle into account when booking exam may cut need for repeat scans, study suggests  Using a blood test to pinpoint the optimal timing of breast MRI scans in women with irregular menstrual cycles could reduce the need for repeat scans, U.S. researchers say.
Previous studies have found that performing breast MRI scans during the follicular phase (days 3 to14) of the menstrual cycle minimizes breast tissue enhancement. | | Key molecule identified by researchers  Researchers may be moving closer to better treatments for bovine spongiform encephalopathy, better known as mad cow disease, and the related condition called Creutzfeldt Jakob disease.
