The Computed Tomography Syndesmophyte Score (CTSS) was developed as a reliable and sensitive tool to assess syndesmophytes in low-dose CT images of the entire spine in patients with axial spondyloarthritis (axSpA). The original paper provided sparce examples of the CTSS grades.
Provide an atlas tailored to assist readers in understanding and employing the CTSS method.
In this paper, illustrations of the different grades and views of the CTSS are presented. CTSS is used to measure bone formation in the spine of patients with axial spondyloarthritis (axSpA), in the form of syndesmophytes. In both the sagittal and coronal planes, syndesmophytes can be graded from 0 to 3 over 23 vertebral units starting at C2 and ending at S1. The CTSS ranges from 0 (absence of axSpA-related syndesmophytes) to 552 (total ankylosis of the spine).
The current atlas contains low-dose CT images of the spine without lesions (for reference) and all grades of syndesmophytes in different planes used in the CTSS. Examples are arranged per spinal segment (cervical, thoracic and lumbar).
These images can be used to assist any reader in the assessment of syndesmophytes on (low-dose) CT in patients with axSpA.
计算机断层扫描骨桥评分（CTSS）是一种可靠且敏感的工具，可用于评估中轴型脊柱关节炎（axSpA）患者全脊柱低剂量 CT 图像中的骨桥。原始论文仅提供了 CTSS 分级的少量示例。
提供一个图谱，旨在帮助读者理解和应用 CTSS 方法。
本文展示了不同 CTSS 分级和视图的图像。CTSS 用于测量 axSpA 患者脊柱中的骨形成情况，以骨桥的形式表现。在矢状面和冠状面，从 C2 到 S1 的 23 个椎体单元上，骨桥可从 0 级到 3 级进行分级。CTSS 的范围从 0（无 axSpA 相关的骨桥）到 552（脊柱完全强直）。
目前的图谱包含无病变的脊柱低剂量 CT 图像（供参考），以及 CTSS 中不同平面的所有骨桥分级。示例按脊柱节段（颈椎、胸椎和腰椎）排列。
这些图像可用于帮助任何读者评估 axSpA 患者（低剂量）CT 上的骨桥。
