http://tinyurl.com/2fbujn The New York Times Call to Increase M.R.I. Use for Breast Exam Article Tools Sponsored By By DENISE GRADY Published: March 28, 2007 Two reports being published today call for greatly expanded use of M.R.I. scans in women who have breast cancer or are at high risk for it. The recommendations do not apply to most healthy women, who have only an average risk of developing the disease. Even so, the new advice could add a million or more women a year to those who need breast magnetic resonance imaging — a demand that radiologists are not yet equipped to meet, researchers say. The scans require special equipment, software and trained radiologists to read the results, and may not be available outside big cities. Breast M.R.I. costs $1,000 to $2,000, and sometimes more — 10 times the cost of mammography — so a million more scans a year would cost at least $1 billion. It is sometimes covered by insurance and Medicare, sometimes not. One report is a set of new guidelines (by American Cancer Society) for using M.R.I. in women at high risk for breast cancer, and the other is a study in The New England Journal of Medicine showing that in women who have newly diagnosed cancer in one breast, M.R.I. can find tumors in the other breast that mammograms miss. （继续阅读：http://tinyurl.com/2fbujn） 参考资料：ACS http://tinyurl.com/228d47 NEJM http://content.nejm.org/cgi/content/short/NEJMoa065447 --
