摘要
目的研究强直性脊柱炎的CT及MR影像学特征,比较两者的诊断效果。方法选取2011年2月—2012年3月来院就诊的32例AS患者作为研究对象,分别进行CT及MR诊断,分析两者诊断的影像学特征,比较诊断结果。结果 CT检查结果显示3例为0级,4例为Ⅰ级,MR检查结果显示7例为Ⅰ级,差异有统计学意义(χ2=4.67,P<0.05);CT骨质侵蚀及骨质硬化检出率均高于MR,差异有统计学意义(P<0.05)。结论 CT对强直性脊柱炎骶髂关节分级判断准确性较高,MR早期诊断的准确率较高。
Objective To study the characteristics of CT and MR imaging of ankylosing spondylitis and compare the diagnostic results of them. Methods 32 patients with AS admitted in our hospital from February, 2011 to March, 2012 were selected as the subjects. CT and MR imaging were performed in the patients to analyze the two diagnostic imaging characteristics, and the diagnostic results were compared. Results CT examination showed that 3 cases of grade 0, 4 cases of grade I ; MR examination showed that 7 cases of grade I, the difference was statistically significant（X2=4.67, P〈O.05）; bone erosion and osteosclerosis detection rate detected by CT are higher than those detected by MR, the differences were statistically significant（P〈0.05）. Conclusion For ankylosing spondylitis sacroiliac joint, CT has higher classification accuracy of judgment, but MR has higher accuracy rate of early diagnosis of the disease.
