A new study concludes that molecular breast imaging (MBI), a newer form of breast cancer screening also called Breast-Specific Gamma Imaging (BSGI), is superior to the more traditional ultrasound and mammography methods of screening. It's sensitivity to finding breast cancer detection was 91% compared to 74% and 84% for the other two methods (respectively).
The study, published in the January 2012 issue of the American Journal of Roentgenology, compared 1,042 patients from four institutions to find the results. The study used a high resolution BSGI camera against two standard mammography and ultrasound machines and methods.
In many cases, the BSGI was used as a follow up second opinion to an original diagnosis of breast cancer from one of the other two methods. The researchers found that in this case, the BSGI was more reliable in changing false diagnosis for better patient management.
