摘　　要：强直性脊柱炎(AS)是一种慢性炎症性风湿病,严重影像人们生活质量,被称为不死得癌症。骶髂关节炎(Sacroiliitis,SI)是AS的病理标志和早期表现,早期的骶髂关节诊断治疗可以很好地预防强直性脊柱炎的发生。利用深度学习对骶髂关节进行自动分割可以大幅度提高医生的诊断效率,然而目前骶髂关节领域自动分割研究相对匮乏,3D网络也面临计算瓶颈。针对以上问题,提出了一种基于轻量化GEC-3DUnet骶髂关节分割网络。首先,通过将Ghost模块扩展到3D网络以线性运算降低网络的参数量,随后引入轻量化的Coordinate Attention以提高网络的分割精度。在山西白求恩医院提供的数据集中验证实验的准确性。结果表明:Ghost模块可以在大幅减少网络参数的情况下保持网络性能,而Coordinate Attention可以有效提高分割的准确度。GEC-3DUnet为高精度、轻量化的骶髂关节分割提供了解决方案,为骶髂关节的自动分级诊断提供了前提条件,在骶髂关节炎相关研究中具有积极意义。Ankylosing spondylitis(AS)is a chronic inflammatory rheumatic disease that severely influences the quality of life,often referred to as an undying cancer.Sacroiliitis(SI)is a pathological hallmark and early manifestation of AS,and early diagnosis and treatment of sacroiliitis can effectively prevent the onset of ankylosing spondylitis.Utilizing deep learning for automatic sacroiliac joint segmentation can significantly enhance the efficiency of doctors'diagnoses.However,current research on automatic segmentation in the sacroiliac joint field is relatively scarce,and 3D networks face computational bottlenecks.To address these issues,we propose a lightweight GEC-3DUnet sacroiliac joint segmentation network.Firstly,the network extends the Ghost module to a 3D network to reduce the number of network parameters through linear operations.Subsequently,lightweight Coordinate Attention is introduced to improve the network's segmentation accuracy.The accuracy of the experiments was validated on data provided by Shanxi Bethune Hospital.The results indicate that the Ghost module can maintain network performance while significantly reducing the number of parameters,and Coordinate Attention can effectively improve segmentation accuracy.GEC-3DUnet provides a solution for high-precision and lightweight sacroiliac joint segmentation,offering a prerequisite for the automatic grading diagnosis of sacroiliac joints and having positive implications for sacroiliitis-related research.
