examination. When AB-MR imaging was applied to the screening, 420 lesions (88.4%) were still considered negative; a follow-up assessment was recommended for 13 lesions (2.7%) and biopsy was recommended for 42 lesions. Thirty-nine of the 42 biopsies were completed. The addition of AB-MR imaging resulted in 12 cancers being found: 7 were invasive carcinomas ranging in size from 0.6 to 1.0 cm, and 5 were ductal carcinomas in situ. At the 6-month follow-up, 1 additional patient was diagnosed with an invasive ductal carcinoma. Overall, the addition of AB-MR to DBT resulted in a cancer detection rate of 27.4/1000 at the patient level. “We need to start thinking about how to better screen women with dense breasts, and AB-MR is an effective and feasible option,” says lead study author Susan P. Weinstein, MD, an associate professor of radiology at the Hospital of the University of Pennsylvania, in a press release.4 “As even more data come out, there will be a lot of debate about how we should screen women with dense breasts, and how we should pay for it.” She underscores the need for more research to better understand the long-term benefits of improved cancer detection on outcomes such as survival.
