摘要:

目的 构建颏下超声舌骨运动半自动追踪分析流程,评价舌骨位移人工测量信度和半自动追踪测量效度及其分析效率。

方法 2024年10月至2025年8月,在厦门市第五医院招募健康成人46例,完成空吞咽,吞咽5 mL和10 mL中稠度液体吞咽任务,采集414段颏下矢状位超声视频;经视频质量筛查和追踪质控,286段视频纳入配对分析。融合通道与空间可靠性追踪器和第8版小型单阶段目标检测模型(YOLOv8s),搭建半自动追踪流程。采用绝对一致性单次测量模型计算人工测量的重测组内相关系数〔ICC(A,1)〕和测量者间ICC(A,1);以人工复测结果作为参照,计算半自动测量的Pearson相关系数(r)、ICC(A,1)和一致性相关系数(CCC);采用基于受试者聚类的5 000次Bootstrap抽样估计95%置信区间;对比人工测量与半自动流程的累计分析时间。

结果 YOLOv8s独立测试集精确率0.940,召回率0.956;平均精度均值在交并比阈值0.5时为0.974,在0.5~0.95各阈值下的均值为0.609。人工测量舌骨最大水平、垂直位移重测ICC(A,1)分别为0.925和0.912;测量者间ICC(A,1)分别为0.815和0.775。与人工参照对比,半自动测量最大水平位移r = 0.865,ICC(A,1) = 0.843,CCC = 0.843;最大垂直位移r = 0.754,ICC(A,1) = 0.746,CCC = 0.745;水平、垂直方向平均偏倚分别为-0.772 mm、-0.229 mm,95%一致性界限依次为-4.567~3.023 mm、-2.918~2.460 mm。测量者A、B测量累计耗时分别为526 min、713 min;半自动测量流程总耗时155 min,其中数据处理40 min,人工复核115 min。

结论 采用颏下超声视频测量舌骨最大位移信度良好;半自动追踪测量与人工测量具有较好一致性,可显著降低视频分析耗时。

Abstract:

Objective To establish a semi-automated workflow for hyoid motion tracking based on submental ultrasound videos, evaluate the reliability of manual measurements and the validity of semi-automated tracking, and compare the analytical efficiency.

Methods A total of 46 healthy adults were recruited at Xiamen Fifth Hospital from October, 2024 to August, 2025, and performed dry swallows and swallows of 5 mL and 10 mL moderately-thick liquid boluses. A total of 414 sagittal-plane submental ultrasound videos were acquired. After video quality screening and tracking quality-control procedures, 286 videos were included for paired analysis. A semi-automated tracking pipeline was constructed combining the channel-and-spatial-reliability tracker and You Only Look Once version 8 small (YOLO v8s). Intra-class correlation coefficients [ICC(A,1)] based on the absolute-agreement single-measurement model were calculated for test-retest and inter-rater manual measurements. Using the manual repeated-measurement results as the reference standard, Pearson correlation coefficient (r), ICC(A,1) and concordance correlation coefficient (CCC) were computed for the semi-automated measurements. A total of 5 000 subject-clustered bootstrap resamples were performed to calculate 95% confidence intervals. Cumulative analysis time of manual and semi-automated workflows was compared.

Results For the independent test set of YOLOv8s, precision and recall reached 0.940 and 0.956. The mean average precision was 0.974 at an intersection-over-union threshold of 0.5, and 0.609 averaged across thresholds ranging from 0.5 to 0.95. For manual measurements of maximum horizontal and vertical hyoid displacement, the test-retest ICC(A,1) values were 0.925 and 0.912, respectively; the inter-rater ICC(A,1) values were 0.815 and 0.775. For semi-automated versus manual reference measurements, r = 0.865,ICC(A,1) = 0.843,CCC = 0.843 in maximum horizontal displacement; and r = 0.754,ICC(A,1) = 0.746,CCC = 0.745 in maximum vertical displacement. Mean biases were -0.772 mm and -0.229 mm, with 95% limits of agreement of -4.567 to 3.023 mm and -2.918 to 2.460 mm for horizontal and vertical directions. Cumulative manual analysis time was 526 minutes for rater A and 713 minutes for rater B. The semi-automated workflow consumed 155 minutes, in which 40 minutes for computational processing and 115 minutes for manual review.

Conclusion Manual measurement of maximum hyoid displacement is reliable using qualified submental ultrasound videos. Semi-automated tracking achieves acceptable agreement with manual reference and greatly reduces analysis workload.
