The Value of Dual-source CT Dual-energy Imaging in the Diagnosis of Gouty Arthritis
-
摘要: 目的：通过采用双源CT（DSCT）双能量成像技术对关节炎患者的发病关节进行检测，探讨DSCT在痛风性关节炎的诊断价值。方法：采用DSCT对来我院就诊的160例关节炎患者的发病关节进行双能量扫描，利用仪器配置的痛风识别软件处理原始图像，由两名临床经验丰富的影像医师对获得的图像进行分析，判断患者受检部位是否有尿酸盐结晶沉积，随后通过病例追踪随访，与临床确诊病例进行对比，分析DSCT技术对痛风的筛查、早期诊断及鉴别诊断的准确率。结果：160例关节炎患者，其中临床诊断为痛风性关节炎136例（33例为急性关节炎期，57例为间歇期急性发作，46例为慢性关节炎期），非痛风性关节炎24例。在136例痛风性关节炎患者中，有124例患病关节内有尿酸盐沉积，痛风性关节炎的检出率为124/136（91.2%）；急性关节炎期33例，其中28例关节内有尿酸盐沉积，检出率为28/33（84.8%）；在24例非痛风性关节炎患者中，24例均未检测出尿酸盐结晶沉积。结论：应用DSCT技术对关节炎患者的发病关节进行扫描，可有效提高临床对于痛风性关节炎的筛查、早期诊断及鉴别诊断的准确率。Abstract: Objective: To explore the diagnostic value of DSCT in gout arthritis. Methods: Scanning 160 patients with arthritis joint in our hospital using dual-source CT with dual-energy and taking advantage of the configuration instrument with gout recognition software to process the original image, there were two experienced clinical imaging doctors with high qualifications analyzing the obtained images to determine whether there was urate crystal deposition within patients' inspection area. Subsequently, through following up cases and comparing with clinical diagnosis, they analyzed the accuracy of DSCT technique for the screening, early diagnosis and differential diagnosis of gout. Results: In the DSCT examination of those 136 patients with gout, 124 cases were found in the joints with urate crystal deposition and the detection rate of gout was 124/136 (91.2%). Among those patients, 28 out of 33 who have acute arthritis, were found by DSCT examination that there was uric acid deposition in their affected joint, and the detection rate of early gout was 28/33 (84.8%). Within 24 patients with non-gout, 24 were not found to have urate crystal deposition. Conclusion: Scanning the pathogenesis of arthritic patients using DSCT technique could effectively improve the accuracy of screening, early diagnosis and differential diagnosis of gout.
