Abstract

Osteoarthritis (OA) is a prevalent disease and the leading cause of pain, disability, and quality of life deterioration. Our study sought to evaluate the image quality and dose of cone-beam computed tomography arthrography (CBCT-A) and compare them to digital radiography (DR) for OA diagnoses. Overall, 32 cases of CBCT-A and DR with OA met the inclusion criteria and were prospectively analyzed. The Kellgren and Lawrence classification (KLC) stage, sclerosis, osteophytes, erosions, and mean joint width (MJW) were compared between CBCT-A and DR. Image quality was excellent in all CBCT-A cases, with excellent inter-observer agreement. OA under-classification was noticed with DR for MJW (p = 0.02), osteophyte detection (<0.0001), and KLC (p < 0.0001). The Hounsfield Unit (HU) values obtained for the cone-beam computed tomography CBCT did not correspond to the values for multi-detector computed tomography (MDCT), with a greater mean deviation obtained with the MDCT HU for Modeled Based Iterative Reconstruction 1st (MBIR1) than for the 2nd generation (MBIR2). CBCT-A has been found to be more reliable for OA diagnosis than DR as revealed by our results using a three-point rating scale for the qualitative image analysis, with higher quality and an acceptable dose. Moreover, the use of this imaging technique permits the preoperative assessment of extremities in an OA diagnosis, with the upright position and bone microarchitecture analysis being two other advantages of CBCT-A.

锥形束计算机断层扫描 CT 四肢关节造影在骨关节炎术前评估中的作用。

骨关节炎（OA）是一种常见疾病，也是导致疼痛、残疾和生活质量下降的主要原因。我们的研究旨在评估锥束计算机断层扫描关节造影术（CBCT-A）的图像质量和剂量，并将其与数字放射摄影术（DR）在诊断 OA 方面进行比较。共有 32 例 CBCT-A 和 DR OA 患者符合纳入标准，并进行了前瞻性分析。对 CBCT-A 和 DR 的 Kellgren 和 Lawrence 分类（KLC）分期、硬化、骨质增生、侵蚀和平均关节宽度（MJW）进行了比较。所有 CBCT-A 病例的图像质量都很好，观察者之间的一致性也很好。在关节平均宽度（MJW）（p = 0.02）和骨质增生检测（p < 0.0001）方面，DR 发现 OA 分级不足。锥束计算机断层扫描 CBCT 的 HU 值与多探头计算机断层扫描 MDCT 的 HU 值不一致，第一代基于模型的迭代重建（MBIR1）与第二代（MBIR2）的 MDCT HU 平均偏差更大。我们采用三点评分法对图像进行定性分析，结果发现 CBCT-A 在诊断 OA 方面比 DR 更可靠，质量更高，剂量也可接受。此外，在诊断 OA 时，使用这种成像技术还可以对四肢进行术前评估，直立体位和骨微结构分析是 CBCT-A 的另外两个优势。

期刊介绍： TomographyTM publishes basic (technical and pre-clinical) and clinical scientific articles which involve the advancement of imaging technologies. Tomography encompasses studies that use single or multiple imaging modalities including for example CT, US, PET, SPECT, MR and hyperpolarization technologies, as well as optical modalities (i.e. bioluminescence, photoacoustic, endomicroscopy, fiber optic imaging and optical computed tomography) in basic sciences, engineering, preclinical and clinical medicine. Tomography also welcomes studies involving exploration and refinement of contrast mechanisms and image-derived metrics within and across modalities toward the development of novel imaging probes for image-based feedback and intervention. The use of imaging in biology and medicine provides unparalleled opportunities to noninvasively interrogate tissues to obtain real-time dynamic and quantitative information required for diagnosis and response to interventions and to follow evolving pathological conditions. As multi-modal studies and the complexities of imaging technologies themselves are ever increasing to provide advanced information to scientists and clinicians. Tomography provides a unique publication venue allowing investigators the opportunity to more precisely communicate integrated findings related to the diverse and heterogeneous features associated with underlying anatomical, physiological, functional, metabolic and molecular genetic activities of normal and diseased tissue. Thus Tomography publishes peer-reviewed articles which involve the broad use of imaging of any tissue and disease type including both preclinical and clinical investigations. In addition, hardware/software along with chemical and molecular probe advances are welcome as they are deemed to significantly contribute towards the long-term goal of improving the overall impact of imaging on scientific and clinical discovery.
