摘要
Background Indications for breast magnetic resonance imaging (MRI), a very sensitive but less-specific tool for breast investigation, remain controversial, and accessibility is limited. The purposes of our study were to determine the proportion of breast MRI exams performed for various clinical indications, to assess the wait times for breast MRI, and to create a list of evidence-based indications for breast MRI. Methods The indications for breast MRI exams performed in September 2013 at our academic centre were audited. A multidisciplinary meeting held in May 2014 established a list of evidence-based indications for breast MRI, after which, in September 2014 and 2015, breast MRI exams were re-audited for clinical indications, and pending requests were calculated. Results In September 2013, surveillance of women with a prior diagnosis of breast cancer represented 21% of breast MRI exams (24 of 113), with preoperative staging representing 18% of exams (20 of 113) and high-risk screening representing 12% (13 of 113). Of pending MRI requests, 230 were within the recommended delay period, and 457 exceeded the recommended delay. After elaboration of evidence-based guidelines, repeat audits in September 2014 and September 2015 showed that MRI performed for women with a prior breast cancer diagnosis represented 23% (33 of 141) and 7% (10 of 143) of exams respectively, with preoperative staging having declined to 9% (13 of 141) and 11% (16 of 143) of exams, and high-risk screening having increased to 36% (51 of 141) and 46% (66 of 143) of exams. Overall, wait times were improved for all breast MRI indications. Conclusions Through multidisciplinary discussion, we actualized a list of breast MRI indications, prioritized requests more adequately, and improved wait times.
