To investigate the practice regarding breast MRI exams and breast MRI-guided biopsies in two countries with different health care systems, France and Québec. A 12-item questionnaire was distributed online among radiologists from France and Québec, attempting to determine: demographic characteristics and breast MRI diagnostic and MRI-guided practices (indications, workload, availability, and waiting time assessment).
One hundred and seventy radiologists (France, 132 respondents (28.5%); Quebec, 38 respondents (35.2%)) participated in the survey, most of them based in non-academic centers. Thirty-eight percent of Quebec and 2.3% of French radiologists did not perform breast MRI in their daily practice. Nearly 50% of French and Quebec respondents interpreted 1-10 breast MRI exams per week. Decision-making factors of preoperative MRI were similar in both countries (pathology, age, and breast density), with a heavier emphasis placed on the surgeon's opinion in Quebec (47.8% versus 21.8% (p = 0.009)). Quebec demonstrated a higher waiting time than France (1-2 weeks in 40% versus less than 1 week in 40%). MRI-guided breast biopsies (less than 5 MRI-guided biopsies per week) were being performed by a minority of the respondents (36% in France and 43% in Québec).
Most of radiologists performing breast MRIs work in non-academic institutions in both countries. Waiting time is higher in Quebec, but most of preoperative breast MRIs are performed within 3 weeks in both countries. The surgeon plays an important role in recommending preoperative MRI in Quebec. MRI-guided breast biopsies are not widely available in both countries.
为调查法国和魁北克这两个拥有不同医疗保健系统的国家在乳腺磁共振成像（MRI）检查及MRI引导下活检方面的实际情况。一份包含12个项目的问卷在法国和魁北克的放射科医生中进行了在线发放，旨在确定：人口统计学特征以及乳腺MRI诊断和MRI引导操作（适应证、工作量、可及性和等待时间评估）。
170名放射科医生（法国，132名受访者（28.5%）；魁北克，38名受访者（35.2%））参与了调查，他们大多数就职于非学术中心。38%的魁北克放射科医生和2.3%的法国放射科医生在日常工作中不进行乳腺MRI检查。近50%的法国和魁北克受访者每周解读1 - 10例乳腺MRI检查。两国术前MRI的决策因素相似（病理、年龄和乳腺密度），不过魁北克更重视外科医生的意见（47.8%对21.8%（p = 0.009））。魁北克的等待时间比法国长（40%的患者等待1 - 2周，而法国40%的患者等待时间少于1周）。少数受访者（法国为36%，魁北克为43%）进行MRI引导下的乳腺活检（每周少于5例）。
两国进行乳腺MRI检查的大多数放射科医生都在非学术机构工作。魁北克的等待时间更长，但两国大多数术前乳腺MRI检查都在3周内完成。在魁北克，外科医生在推荐术前MRI检查方面发挥着重要作用。两国MRI引导下的乳腺活检都未广泛开展。
