Abstract

Objectives

To explore the diagnostic value of dual-energy computed tomography (DECT) in patients with gouty arthritis.

Methods

A total of 160 patients with gouty arthritis who were treated in our hospital from January 2023 to October 2023 were selected as the research subjects. The participants were randomly divided into two groups: an observation group and a control group. Each group had 80 cases. Observation group performed DECT examination and control group performed X-ray examination. The researchers recorded the general information of the participants in both groups and conducted single-factor analysis. They compared the detection of positive diseased joints between the two groups, as well as compared the distribution of positive diseased joints. In addition, the number of joint lesions was compared in the two groups.

Results

There were not any statistically great differences between the two groups in gender, age, BMI, disease duration, blood uric acid, and erythrocyte sedimentation rate (p > 0.05). During the DECT examination, a total of 82 positive diseased joints were identified in the observation group. The observation group also had a positive rate of 85.42% (82/96) in the DECT examination. While the control group had a total of 55 positive diseased joints during the X-ray examination with a positive rate of 59.78% (55/92). The difference between the two groups of patients in the positive rate of two kinds of examination was statistically significant (χ2 = 15.616, p < 0.001). No statistical significance was found in the distribution of the number of positive diseased joints between two groups (χ2 = 1.986, p = 0.851). Both DECT and X-ray examinations of patients in the two groups revealed that the lesions were primarily located in the soft tissues or ligaments surrounding the distal small joints of the limbs, such as metatarsophalangeal joints, ankle joints, and proximal interphalangeal joints. Compared with the X-ray examination of the patients, the DECT examination of the patients showed a great increase in the number of bone destruction, gout nodules, and soft tissue swelling (χ2 = 7.712, 10.441, 5.389, p = 0.005, 0.001, 0.020). Moreover, the DECT examination of patients showed the presence of urate crystals and joint effusion, while the X-ray examination of patients in the control group did not show any.

Conclusions

Siemens dual-source 64-slice CT dual-energy imaging has better diagnostic value for gouty arthritis than X-ray and has higher specificity for detecting urate crystals and joint effusion. Therefore, Siemens dual-source 64-slice CT dual-energy imaging examination may serve as a promising new noninvasive technique for early diagnosis, clinical screening, and follow-up of gout in the future.

双能CT (DECT)对痛风性关节炎诊断价值的研究
目的探讨双能计算机断层扫描(DECT)对痛风性关节炎的诊断价值。方法选择2023年1月至2023年10月在我院治疗的痛风性关节炎患者160例作为研究对象。参与者被随机分为两组:观察组和对照组。每组80例。观察组行DECT检查,对照组行x线检查。研究人员记录了两组参与者的一般信息,并进行了单因素分析。他们比较了两组之间阳性病变关节的检出率,以及阳性病变关节的分布。此外,比较两组关节病变的数量。结果两组患者性别、年龄、BMI、病程、血尿酸、血沉比较,差异均无统计学意义(p > 0.05)。在DECT检查中,观察组共发现82个阳性病变关节。观察组DECT检查阳性率为85.42%(82/96)。对照组x线检查阳性病变关节共55个,阳性率为59.78%(55/92)。两组患者两项检查阳性率比较,差异有统计学意义(χ2 = 15.616, p < 0.001)。两组间阳性病变关节数分布差异无统计学意义(χ2 = 1.986, p = 0.851)。两组患者的DECT和x线检查均显示病变主要位于肢体远端小关节周围的软组织或韧带,如跖趾关节、踝关节、近端指间关节。与患者x线检查相比,患者DECT检查显示骨破坏、痛风结节、软组织肿胀明显增加(χ2 = 7.712、10.441、5.389,p = 0.005、0.001、0.020)。此外,患者的DECT检查显示存在尿酸盐晶体和关节积液,而对照组患者的x线检查未见任何变化。结论西门子双源64排CT双能成像对痛风性关节炎的诊断价值优于x线,对尿酸结晶及关节积液的检测特异性更高。因此,西门子双源64排CT双能成像检查有望成为未来痛风早期诊断、临床筛查和随访的无创新技术。
