Practicalities of developing a breast magnetic resonance imaging screening service for women at high risk for breast cancer.

Demand for screening breast magnetic resonance imaging (MRI) for women with a hereditary predisposition to breast cancer has increased since the introduction of a medicare item number. To aid future service planning, we examined the practicalities of establishing and running a breast MRI screening programme for high risk women and to describe the early outcomes of our screening programme.,We undertook a retrospective audit of prospectively collected data. Women <50 years of age with an inherited BRCA1 or BRCA2 gene mutation were invited to undergo annual breast screening with MRI in addition to mammography and clinical breast examination. We assessed process times for booking, performing and reporting MRIs; MRI findings and ease of interpretation; patient recall rate; MRI cancer detection rate; and patient satisfaction via questionnaire.,From 2006 to 2009, 82 women completed a round one screening MRI and 45, 21 and one women completed second, third and fourth round annual MRI studies, respectively. Median MRI process times were: booking 20 min; attendance in radiology department 90 min; imaging duration 45 min; reporting by one radiologist 30 min. Of the 82 round one studies, 23 (28%) were reported as ≥Breast Imaging Reporting and Data System three requiring further investigation. Of the round two and three studies completed, 13/45 (28%) and 2/21 (9%) have been recalled, respectively. Seven malignancies were detected. Questionnaires revealed women were satisfied with the service.,Significant time, staff and equipment is required to run an effective breast MRI screening programme and this must be considered by future service providers.
