摘要: 选取2017年5月~2019年5月于我院就诊的痛风性关节炎患者100例,均行双源CT及MRI检查。通过比较双源CT及MRI对痛风性关节炎的阳性诊断率、诊断灵敏度,以及不同影像学表现的差异(包括痛风结节、关节骨质破坏、关节软骨侵蚀、关节积液、周围间隙水肿、滑膜破坏和尿酸盐结晶等),探讨双源CT和MRI在痛风性关节炎诊断中的应用价值。结果显示,双源CT检出患病关节的阳性率及诊断敏感度均高于MRI,且差异具有统计学意义;双源CT对于痛风结节以及骨质破坏的检出率高于MRI,且差异具有统计学意义;在检测尿酸盐结晶方面,双源CT具有特异性;MRI对于关节积液、关节周围间隙水肿、软骨侵蚀、滑膜侵蚀的检出率高于双源CT,且差异具有统计学意义。上述结果表明双源CT具有尿酸盐结晶诊断特异性,其在痛风性关节炎诊断中的应用价值高于MRI。

Abstract: 100 patients with gouty arthritis who were treated in our hospital from May 2017 to May 2019 were enrolled. All patients underwent dual-source CT and MRI. In this study, we compared the positive diagnostic rate and the diagnostic sensitivity of dual-source CT and MRI, as well as the image differences in two methods(including tophus, joint bone damage, articular cartilage damage, joint effusion, peripheral edema, synovial damage and urate crystal). The aim was to explore the value of dual-source CT and MRI in the diagnosis of patients with gouty arthritis. The results showed that the positive rate and diagnostic sensitivity of dual-source CT were higher than that of MRI, and the difference was statistically significant. Dual-source CT had a higher detection rate for tophus and bone destruction than MRI, and the difference was statistically significant. Dual-source CT has high specificity in detecting urate crystals. In examination of joint effusion, synovium and cartilage change, MRI has higher detection rates than dual-source CT, and the difference was statistically significant. The above results indicate that dual-source CT is specific in diagnosing urate crystals. The application value of dual-source CT in the diagnosis of gouty arthritis is higher than MRI.

Key words: gouty arthritis, dual source CT, MRI
