目的分析高频超声、X线、CT三种影像学检查方法诊断痛风性关节炎的应用价值。方法选取84例痛风性关节炎患者,分别进行高频超声、X线、CT检测,比较三种影像学检查结果。结果 HFUS、CT、X线检查痛风石、关节积液、组织肿胀检出率依次下降,组间差异有统计学意义(P<0.05),仅HFUS检测出41例患者出现滑膜增厚,X线、CT均无检出;HFUS、CT、X线确诊率依次为89.2%、39.3%、57.1%,HFUS灵敏度最高,X线最低,组间差异有统计学意义(P<0.05)。结论高频超声对痛风性关节炎具有较高的灵敏度,诊断符合率显著高于X线、CT,X线确诊率最低,可用于中晚期诊断。
Objective To analyze the value of high-frequency ultrasound, X-ray and CT imaging in the diagnosis of gouty arthritis. Methods Eighty-four patients with gouty arthritis were selected and examined by high-frequency ultrasound, X-ray and CT respectively. The results of three imaging tests were compared. Results The detection rates of tophi, joint effusion and tissue swelling decreased with the increase of HFUS, CT and X-ray. The differences between the two groups were statistically significant (P <0.05). Only HFUS detected 41 patients with synovial thickening, X The positive rates of HFUS, CT and X were 89.2%, 39.3% and 57.1%, respectively. The highest sensitivity of HFUS and the lowest of X-ray were found between the two groups (P <0.05). Conclusion High-frequency ultrasound has high sensitivity to gouty arthritis, the diagnostic coincidence rate is significantly higher than the X-ray, CT, X-ray diagnosis of the lowest rate, can be used in the diagnosis.
