强直性脊柱炎骶髂关节MRI平扫与X线平片、CT分析

Analysis of MRI Scan and X-ray,CT in Ankylosing Spondylitis Sacroiliac Joint

目的探析CT、X线平片及MRI平扫在强直性脊柱炎骶髂关节病变中的临床诊断价值。方法回顾性分析100例我院2014年12月-2015年12月收治的强直性脊柱炎骶髂关节病变患者临床资料,对比分析X线平片、CT及MRI平扫三种影像学资料和病变分级。结果 CT扫描检出率85.0%高于X线平片64.0%,MRI平扫检出率94.0%高于X线平片检出率64.0%,差异具有统计学意义（P〈0.05）;CT扫描检出率85.0%与MRI平扫检出率94.0%比较,差异无统计学意义（P〉0.05）;早期AS骶髂关节病变0-Ⅱ级,其X线平片检出率与CT、MRI分级检出率分别相比较,差异具有统计学意义（P〈0.05）;但对于Ⅲ级与Ⅳ级病变,三种影像学检查方式相似,差异无统计学意义（P〉0.05）。结论早期强直性脊柱炎骶髂关节病变多表现为关节软骨肿胀、骨质疏松、骨质囊变及骨质侵蚀等,而CT与MRI的临床检出准确率较高,尤其是临床中疑似强直性脊柱炎早期病变者,临床CT和MRI检查具有极高的诊断价值。

Objective Analysis of the clinical diagnostic value of the CT,X-ray and MRI scan in ankylosing spondylitis sacroiliac joint. Methods A retrospective analysis of clinical data of 100 cases with ankylosing spondylitis sacroiliac joint lesions admitted in our hospital,from December 2014 to December 2015,and comparative analysis of X-ray,CT scan and MRI imaging data and disease classification. Results The detection rate of CT scan 85.0% was significantly higher than the X-ray 64.0%,and the detection rate of MRI scan 94.0% was significantly higher than the X-ray detection rate of 64.0%,the difference was statistically significant（P〈0.05）. The detection rate of CT scan was 85.0%,the detection rate of MRI 94.0%,the difference was not statistically significant（P〉0.05）. In early AS sacroiliac joint 0 - Ⅱ grade,the comparison of X-ray detection rate and MRI or CT grading detection rate were statistically significant（P〈0.05）,respectively. But for grade Ⅲ and Ⅳ grade lesions,all three imaging in a similar manner,the difference was not statistically significant（P〉0.05）. Conclusion Early ankylosing spondylitis sacroiliac joint more performance articular cartilage swelling,osteoporosis,cystic degeneration and bone erosion,and clinical CT and MRI detection have higher accuracy,especially in clinical suspected early ankylosing spondylitis lesions,the clinical CT and MRI has a very high diagnostic value.
