通过多器官分割提升冠脉钙化评分准确率与可解释性

Enhancing Coronary Artery Calcium Scoring via Multi-Organ Segmentation on Non-Contrast Cardiac Computed Tomography

  • 基于解剖结构理解而非病变检测,改进钙化评分方法
  • 在多厂商数据集上达到人医生水平的准确性
  • 适合心血管影像分析与临床辅助诊断研究者

尽管冠状动脉钙化评分在医学人工智能领域被视为已解决的问题,本文认为仍存在显著提升空间。通过将重点从病理检测转向解剖结构的深层理解,提出的新算法不仅实现了高精度的冠脉钙化评分,还提升了结果的可解释性。该方法不仅能精确量化冠脉钙化,还为心臟解剖结构提供了重要洞察。基于这一解剖引导的方法,研究展示了对心脏结构的细致理解如何带来更准确、更可解释的冠心病评估。我们在一个开源多厂商数据集上评估该方法,结果达到人医生间一致性水平,超越当前最先进水平。定性分析表明,该算法在冠脉钙化标注、主动脉钙化识别及噪声导致的假阳性过滤方面具有实际应用价值。

原文摘要 · Abstract (English)

Despite coronary artery calcium scoring being considered a largely solved problem within the realm of medical artificial intelligence, this paper argues that significant improvements can still be made. By shifting the focus from pathology detection to a deeper understanding of anatomy, the novel algorithm proposed in the paper both achieves high accuracy in coronary artery calcium scoring and offers enhanced interpretability of the results. This approach not only aids in the precise quantification of calcifications in coronary arteries, but also provides valuable insights into the underlying anatomical structures. Through this anatomically-informed methodology, the paper shows how a nuanced understanding of the heart's anatomy can lead to more accurate and interpretable results in the field of cardiovascular health. We demonstrate the superior accuracy of the proposed method by evaluating it on an open-source multi-vendor dataset, where we obtain results at the inter-observer level, surpassing the current state of the art. Finally, the qualitative analyses show the practical value of the algorithm in such tasks as labeling coronary artery calcifications, identifying aortic calcifications, and filtering out false positive detections due to noise.
