The objective of our study was to report on the current practices of radiologists involved in the performance and interpretation of breast MRI in the United States.
We invited the 1,696 active physician members of the Society of Breast Imaging to participate in a survey addressing whether and how they performed and interpreted breast MRI. Respondents were asked to select one member of their practice to complete the survey. A total of 754 surveys were completed. Every respondent did not reply to every question.
Contrast-enhanced breast MRI was offered at 557 of 754 (73.8%) practices. Of these, 346 of 553 (62.6%) performed at least five breast MRI examinations per week, and only 56 of 553 (10.1%) performed > 20 per week. Radiologists qualified under the Mammography Quality Standards Act supervised the performance of and interpreted breast MRI in the majority of facilities. Of 552 respondents, breast MRI was interpreted as soft copy with computer-aided detection (CAD) in 280 practices (50.7%), as soft copy without CAD in 261 (47.3%), and as hard copy in 11 (2.0%). Of 551 respondents, 256 (46.5%) never and 207 (37.6%) rarely interpreted breast MRI without correlating mammography or sonography findings. The majority of respondents never (269/561, 48.0%) or rarely (165/561, 29.4%) interpreted breast MRI performed at an outside facility. Screening breast MRI was offered at 359 of 561 (64.0%) practices. Of the practices performing contrast-enhanced examinations, 173 of 557 (31.1%) did not perform MRI-guided interventional procedures.
Contrast-enhanced breast MRI is now widely used in the United States. The information gained from this survey should provide reasonable approaches for the development of professional practice guidelines.
我们研究的目的是报告美国参与乳腺MRI检查及解读的放射科医生的当前做法。
我们邀请了乳腺影像学会的1696名在职医生会员参与一项关于他们是否以及如何进行乳腺MRI检查及解读的调查。要求受访者选择他们科室的一名成员来完成调查。共完成了754份调查问卷。并非每位受访者都回答了每个问题。
754个科室中有557个（73.8%）提供对比增强乳腺MRI检查。其中，553个科室中有346个（62.6%）每周至少进行5例乳腺MRI检查，而553个科室中只有56个（10.1%）每周进行超过20例检查。在大多数机构中，符合《乳腺摄影质量标准法案》资格的放射科医生监督乳腺MRI检查的操作并进行解读。在552名受访者中，280个科室（50.7%）将乳腺MRI解读为带有计算机辅助检测（CAD）的软拷贝，261个科室（47.3%）解读为不带有CAD的软拷贝，11个科室（2.0%）解读为硬拷贝。在551名受访者中，256名（46.5%）从不，207名（37.6%）很少在不关联乳腺X线摄影或超声检查结果的情况下解读乳腺MRI。大多数受访者从不（269/561，48.0%）或很少（165/561，29.4%）解读在外部机构进行的乳腺MRI。561个科室中有359个（64.0%）提供乳腺MRI筛查。在进行对比增强检查的科室中，557个科室中有173个（31.1%）不进行MRI引导的介入操作。
对比增强乳腺MRI目前在美国广泛使用。从本次调查中获得的信息应为制定专业实践指南提供合理方法。
