DR、螺旋CT对强直性脊柱炎骶髂关节病变征象显示情况分析及应用价值探讨

DR,spiral CT on the analysis and Discussion on the application value of sacroiliac joint in ankylosing spondylitis signs

目的:探讨强直性脊柱炎骶髂关节病变的DR、螺旋CT各种影像学表现及其临床应用价值。方法:对97例强直性脊柱炎骶髂关节病变患者,均行DR及多层螺旋CT检查。比较两者对疾病的检出情况及对各种征象的显示情况。结果:螺旋CT检查对0级、Ⅰ级、Ⅱ级病变患者所占比例分别为0%、24.7%、39.2%,DR检查分别为15.5%、13.4%、25.8%,二者比较,差异具有统计学意义(P<0.05)。CT显示关节面侵蚀81例(83.5%),关节面下骨质囊变63例(64.9%),骨质增生硬化65例(67.0%),关节周围软组织肿胀21例(21.6%),其比例均明显高于DR组的57例(58.7%)、39例(40.2%)、53例(54.6%)和4例(4.1%),差异有统计学意义(P<0.05)。结论:螺旋CT对诊断强直性脊柱炎骶髂关节病变较DR更具有很高的应用价值。

Objective To investigate the ankylosing spondylitis sacroiliac joint lesions in DR,spiral CT imaging findings and its clinical application value. Method 97 cases of sacroiliac joint in ankylosing spondylitis patients, underwent DR and multi - slice spiral CT examination. Compared to detect the disease and the various signs show. Results Spiral CT examination for grade 0 ,grade Ⅰ ,the grade Ⅱ lesions were respectively 0% ,24.7%0,39. 2%, DR respectively 15.5 %, 13.4%, 25.8%. Comparing the two of them, the difference was statistically significant （ P 〈 0. 05 ） . CT showed the articular surface erosion in 81 cases （83.5%） , articular surface bone cyst in 63 cases （64. 9% ） ,bone sclerosis in 65 cases （67%）, soft tissue swelling in 21 cases （21.6%）, which were significantly higher than those in group DR 57 cases （58. 7% ） ,39 cases （40. 2% ） ,53 cases （54. 6% ） and 4 cases （4. 1% ） ,the difference was statistically significant （ P 〈 0.05 ）. Conclusion Spiral CT has higher application value in the diagnosis of sacroiliac joint in ankylosing soondylitis than DR.
