Abstract

Abdominal aortic aneurysm (AAA) often remains undetected until rupture due to limited access to diagnostic ultrasound. This trial evaluated a deep learning (DL) algorithm to guide AAA screening by novice nurses with no prior ultrasonography experience. Ten nurses performed 15 scans each on patients over 65, assisted by a DL object detection algorithm, and compared against physician-performed scans. Ultrasound scan quality, assessed by three blinded expert physicians, was the primary outcome. Among 184 patients, DL-guided novices achieved adequate scan quality in 87.5% of cases, comparable to the 91.3% by physicians (p = 0.310). The DL model predicted AAA with an AUC of 0.975, 100% sensitivity, and 97.8% specificity, with a mean absolute error of 2.8 mm in predicting aortic width compared to physicians. This study demonstrates that DL-guided POCUS has the potential to democratize AAA screening, offering performance comparable to experienced physicians and improving early detection.

用于腹主动脉瘤超声筛查的深度学习前瞻性临床评估
由于接受超声诊断的机会有限,腹主动脉瘤(AAA)往往在破裂前一直未被发现。这项试验对深度学习(DL)算法进行了评估,以指导没有超声波检查经验的新手护士进行 AAA 筛查。在深度学习物体检测算法的辅助下,10 名护士分别对 65 岁以上的患者进行了 15 次扫描,并与医生进行的扫描进行了比较。超声扫描质量是主要结果,由三位盲法专家医师进行评估。在 184 名患者中,DL 引导的新手在 87.5% 的病例中达到了适当的扫描质量,与医生 91.3% 的扫描质量相当(p = 0.310)。DL 模型预测 AAA 的 AUC 为 0.975,灵敏度为 100%,特异性为 97.8%,与医生相比,预测主动脉宽度的平均绝对误差为 2.8 毫米。这项研究表明,DL 引导的 POCUS 有可能实现 AAA 筛查的民主化,其效果可与经验丰富的医生媲美,并能提高早期检测率。
