To evaluate uptake, patterns of use, and perception of digital breast tomosynthesis (DBT) among practicing breast radiologists.
Institutional Review Board exemption was obtained for this Health Insurance Portability and Accountability Act-compliant electronic survey, sent to 7023 breast radiologists identified via the Radiological Society of North America database. Respondents were asked of their geographic location and practice type. DBT users reported length of use, selection criteria, interpretive sequences, recall rate, and reading time. Radiologist satisfaction with DBT as a diagnostic tool was assessed (1-5 scale).
There were 1156 (16.5%) responders, 65.8% from the United States and 34.2% from abroad. Of these, 749 (68.6%) use DBT; 22.6% in academia, 56.5% private, and 21% other. Participants are equally likely to report use of DBT if they worked in academics versus in private practice (78.2% [169 of 216] vs 71% [423 of 596]) (odds ratio, 1.10; 95% confidence interval: 0.87-1.40; P = 1.000). Of nonusers, 43% (147 of 343) plan to adopt DBT. No US regional differences in uptake were observed (P = 1.000). Although 59.3% (416 of 702) of DBT users include synthetic 2D (s2D) for interpretation, only 24.2% (170 of 702) use s2D alone. Majority (66%; 441 of 672) do not perform DBT-guided procedures. Radiologist (76.6%) (544 of 710) satisfaction with DBT as a diagnostic tool is high (score ≥ 4/5).
DBT is being adopted worldwide across all practice types, yet variations in examination indication, patient selection, utilization of s2D images, and access to DBT-guided procedures persist, highlighting the need for consensus and standardization.
评估执业乳腺放射科医生对数字乳腺断层合成（DBT）的接受程度、使用模式及看法。
对于这项符合《健康保险流通与责任法案》的电子调查，已获得机构审查委员会的豁免。该调查发送给通过北美放射学会数据库识别出的7023名乳腺放射科医生。询问了受访者的地理位置和执业类型。DBT使用者报告了使用时长、选择标准、解读顺序、召回率及阅片时间。评估了放射科医生对DBT作为诊断工具的满意度（1 - 5分制）。
有1156名（16.5%）受访者，65.8%来自美国，34.2%来自国外。其中，749名（68.6%）使用DBT；22.6%在学术界，56.5%在私立机构，21%在其他机构。如果在学术界工作与在私立机构工作，参与者报告使用DBT的可能性相同（78.2%[216人中的169人]对71%[596人中的423人]）（优势比，1.10；95%置信区间：0.87 - 1.40；P = 1.000）。在未使用者中，43%（343人中的147人）计划采用DBT。未观察到美国在接受程度上的地区差异（P = 1.000）。尽管59.3%（702人中的416人）的DBT使用者在解读时包括合成二维（s2D），但只有24.2%（702人中 的170人）单独使用s2D。大多数（66%；672人中的441人）不进行DBT引导的操作。放射科医生（76.6%）（710人中的544人）对DBT作为诊断工具的满意度较高（评分≥4/5）。
DBT正在全球范围内被各类执业机构采用，但在检查指征、患者选择、s二维图像的利用以及获得DBT引导的操作方面仍存在差异，这凸显了达成共识和标准化的必要性。
