首个公开的脊髓超声数据集,支持损伤定位与解剖分割的深度学习研究。

A novel open-source ultrasound dataset with deep learning benchmarks for spinal cord injury localization and anatomical segmentation

  • 构建10,223张猪脊髓超声图像数据集,涵盖损伤前后状态。
  • YOLOv8在损伤定位上表现最佳,mAP50-95达0.606;DeepLabv3分割精度最高(Dice=0.587)。
  • 首次验证模型在人类数据上的零样本泛化能力,助力临床转化。

尽管深度学习已在多个领域取得突破,但其在临床中的广泛应用仍受限于数据采集和标注的成本与耗时。为推动医学机器学习发展,我们发布了一个包含10,223幅亮度模式(B-mode)图像的开源超声数据集,涵盖25只猪的矢状面脊髓图像,覆盖损伤前后的状态。我们还评估了多种先进目标检测算法在损伤定位上的表现,以及语义分割模型在解剖结构标注上的性能,用于对比并指导任务专用架构的设计。此外,我们测试了分割模型在人类脊髓超声图像上的零样本泛化能力,以评估基于猪数据训练的模型是否足以准确解析人类数据。结果表明,YOLOv8在损伤定位中表现最优,平均精度(mAP50-95)达0.606;DeepLabv3在未见猪脊髓图像上分割精度最高,平均Dice系数为0.587;而SAMed在人类数据上泛化表现最佳,平均Dice系数为0.445。据我们所知,这是目前公开可用的最大规模脊髓超声图像标注数据集,也是首个公开报告的用于评估脊髓解剖标记的目标检测与分割架构,为方法开发与临床应用提供重要支持。

原文摘要 · Abstract (English)

While deep learning has catalyzed breakthroughs across numerous domains, its broader adoption in clinical settings is inhibited by the costly and time-intensive nature of data acquisition and annotation. To further facilitate medical machine learning, we present an ultrasound dataset of 10,223 Brightness-mode (B-mode) images consisting of sagittal slices of porcine spinal cords (N=25) before and after a contusion injury. We additionally benchmark the performance metrics of several state-of-the-art object detection algorithms to localize the site of injury and semantic segmentation models to label the anatomy for comparison and creation of task-specific architectures. Finally, we evaluate the zero-shot generalization capabilities of the segmentation models on human ultrasound spinal cord images to determine whether training on our porcine dataset is sufficient for accurately interpreting human data. Our results show that the YOLOv8 detection model outperforms all evaluated models for injury localization, achieving a mean Average Precision (mAP50-95) score of 0.606. Segmentation metrics indicate that the DeepLabv3 segmentation model achieves the highest accuracy on unseen porcine anatomy, with a Mean Dice score of 0.587, while SAMed achieves the highest Mean Dice score generalizing to human anatomy (0.445). To the best of our knowledge, this is the largest annotated dataset of spinal cord ultrasound images made publicly available to researchers and medical professionals, as well as the first public report of object detection and segmentation architectures to assess anatomical markers in the spinal cord for methodology development and clinical applications.
