【摘要】：目的:比较X线、CT和MRI检查对痛风性关节炎的诊断价值。方法:回顾性分析56例痛风性关节炎患者共112个患病关节的X线、CT和MRI影像资料,采用卡方检验对比分析3种检查方法的检出率及对不同病变的显示率。结果:X线、CT、MRI检查的检出率分别为53%(59/112)、74%(83/112)、88%(99/112),MRI高于CT、X线(χ2=7.502,P=0.006;χ2=34.369,P0.001)。X线显示痛风结节、关节面下囊变的关节个数少于MRI(χ2=24.605,P0.001;χ2=31.112,P0.001)和CT(χ2=18.576,P0.001;χ2=13.069,P0.001)。CT检查显示痛风结节和关节面下囊变的关节个数与MRI比较差异无统计学意义(χ2=0.466,P=0.495;χ2=3.211,P=0.073),但显示关节滑膜及韧带侵蚀、关节软骨侵蚀、关节积液和关节周围肌间隙水肿的关节个数均少于MRI(χ2=19.790,P0.001;χ2=11.568,P0.001;χ2=13.297,P0.001;χ2=6.720,P=0.01)。结论 :X线、CT和MRI对痛风性关节炎均有较好的诊断能力,其中MRI检查总的检出率较高、发现病变的能力较好,CT检查则对痛风结节具有较高的特异性,而X线适用于中晚期患者的复查对照。
[Abstract]:Objective: to compare the value of X-ray CT and MRI in the diagnosis of gouty arthritis. Methods: the X-ray CT and MRI images of 112 joints in 56 patients with gouty arthritis were analyzed retrospectively. Using chi-square test, the detection rate of three methods and the display rate of different lesions were analyzed comparatively. Results the detectable rate of CT MRI was 5359 / 112 / 74% respectively, which was higher than that of CTX radiography (蠂 2 + 7.502P 0.006; 蠂 2 34.369U P 0.001n .X), and was higher than that of CTX X ray (蠂 2 + 7.502P 0.006; 蠂 2 34.369U P 0.001N. X). The detection rate of MRI was higher than that of CTX X ray (蠂 2 7.502P 0.006; 蠂 2 34.369U P 0.001n 路X ray). The number of joints with subarticular cystic degeneration was less than that of MRI (蠂 ~ 2 ~ 2 ~ 2 ~ (24) 605 ~ (5) P ~ (0.001); 蠂 ~ (2) 21 ~ (31) 1 ~ (12) P _ (0.001)) and CT (蠂 ~ (2)) (蠂 ~ (2)) ~ (18. 576) P ~ (0.001); 蠂 ~ (2 +) ~ (13) 069 (P ~ (0.001)) P ~ (0.001). Ct showed no significant difference in the number of joints between gout nodules and subarticular cysts compared with MRI (蠂 ~ (2) 0.466p ~ (0.495); 蠂 ~ (3.21111) P ~ (0.073)), but it showed joint synovial and ligament erosion, articular cartilage erosion. The number of joints in joint effusion and periarticular muscle space edema was less than that of MRI (蠂 2 + 19.790% P 0.001; 蠂 2 + 11.568 P 0.001; 蠂 2 + 13.297 P 0.001; 蠂 2 + 6.720% P 0. 01). Conclusion both X-ray CT and MRI have better diagnostic ability for gouty arthritis, and the detection rate of MRI is higher. The ability of finding lesions was better and CT examination had higher specificity for gout nodules, and X-ray was suitable for the reexamination control of middle and late stage patients.
