用AI自动分割心脏脂肪,精度超97%,实时处理临床可用。

Cardiac fat segmentation using computed tomography and an image-to-image conditional generative adversarial neural network

  • 用pix2pix生成对抗网络实现心脏脂肪图像到分割图的端到端转换。
  • 心外膜脂肪分割准确率99.08%,纵隔脂肪97.90%,F1均超98%。
  • 速度快可实时分割,适合临床快速定量分析心脏脂肪。

近年来研究发现,心脏周围脂肪组织增多与房颤、冠心病等心血管疾病风险升高相关。但人工手动分割这些脂肪沉积因工作量大、成本高,尚未广泛应用于临床。因此,亟需更精准高效的定量分析方法。本研究提出一种基于深度学习的新方法,可自主分割并量化两类心脏脂肪:心外膜脂肪和纵隔脂肪(由心包分隔)。该方法采用pix2pix网络——一种主要用于图像到图像翻译的条件生成对抗网络,尽管其非专为医学分割设计。实验结果显示,心外膜脂肪分割平均准确率达99.08%,F1分数为98.73;纵隔脂肪准确率为97.90%,F1分数为98.40。结果表明该方法具有极高的精度与重叠一致性。相比现有研究,本方法在F1分数和运行时间上均表现更优,支持实时分割。

原文摘要 · Abstract (English)

In recent years, research has highlighted the association between increased adipose tissue surrounding the human heart and elevated susceptibility to cardiovascular diseases such as atrial fibrillation and coronary heart disease. However, the manual segmentation of these fat deposits has not been widely implemented in clinical practice due to the substantial workload it entails for medical professionals and the associated costs. Consequently, the demand for more precise and time-efficient quantitative analysis has driven the emergence of novel computational methods for fat segmentation. This study presents a novel deep learning-based methodology that offers autonomous segmentation and quantification of two distinct types of cardiac fat deposits. The proposed approach leverages the pix2pix network, a generative conditional adversarial network primarily designed for image-to-image translation tasks. By applying this network architecture, we aim to investigate its efficacy in tackling the specific challenge of cardiac fat segmentation, despite not being originally tailored for this purpose. The two types of fat deposits of interest in this study are referred to as epicardial and mediastinal fats, which are spatially separated by the pericardium. The experimental results demonstrated an average accuracy of 99.08% and f1-score 98.73 for the segmentation of the epicardial fat and 97.90% of accuracy and f1-score of 98.40 for the mediastinal fat. These findings represent the high precision and overlap agreement achieved by the proposed methodology. In comparison to existing studies, our approach exhibited superior performance in terms of f1-score and run time, enabling the images to be segmented in real time.
