In Review - News from the 2005 Meeting of the RSNAAdjunctive technique improves sensitivity, specificityBy: Emily HayesA new method of computer-aided evaluation makes it easier to differentiate between benign and malignant lesions on MR scans, possibly reducing the number of false positives and unnecessary biopsies. Other findings include: - Computer-aided detection is no match for a dedicated breast imaging specialist, according to a large comparative study of 5875 consecutive screening mammograms performed at Yale's Breast Imaging Center. - Breast MR spectroscopy as an adjunct to breast MR may cut the rate of false positives related to the stage of a woman's menstrual cycle. - In the Digital Mammographic Imaging Screening Trial (DMIST), 40% of the women over 50 had dense breasts, indicating that digital screening could benefit older as well as younger women. - DMIST researchers plan to investigate why there was a difference between digital and film-based screening and will also perform a cost-effectiveness study for digital imaging. |
