目的探讨磁共振(MRI)检查对早期强直性脊柱炎(AS)骶髂关节病变的诊断价值。方法选取河南能源鹤煤集团总医院2013年2月—2015年2月收治的AS患者78例,分别予以MRI、X线及CT检查并进行对比分析。结果 MRI检查对关节面侵蚀、关节面下骨质囊变检出率高于X线和CT检查,差异有统计学意义(P<0.05);MRI检查对关节软骨肿胀检出率与CT检查比较,差异无统计学意义(P>0.05),但与X线检查检出率比较,差异有统计学意义(P<0.05)。MRI检查对AS 0级检出率高于X线和CT检查,差异有统计学意义(P<0.05);MRI和CT检查对ASⅠ、Ⅱ级检出率均高于X线检查,差异有统计学意义(P<0.05)。结论 MRI检查对早期AS骶髂关节病变显示具有明显优势,可更好的检出软组织病变,且能显示低级别的AS。
Objective To investigate the value of magnetic resonance imaging (MRI) in the diagnosis of sacroiliac joint disease in ankylosing spondylitis (AS). Methods Totally 78 AS patients who were treated in Henan General Hospital of Hebi Coal Group from February 2013 to February 2015 were examined by MRI, X-ray and CT respectively. Results The MRI examination showed that the detection rate of articular surface erosion and articular surface bone mass was higher than that of X-ray and CT (P <0.05). MRI examination showed that the detection rate of articular cartilage swelling was significantly lower than that of CT (P> 0.05), but the difference was statistically significant compared with X-ray examination (P <0.05). The detection rate of AS 0 in MRI examination was higher than that in X-ray examination and CT examination (P <0.05). The detection rates of ASⅠ and Ⅱ were higher than those of X-ray examination by MRI and CT Significance (P <0.05). Conclusion MRI examination showed obvious advantages in the early stage of AS and sacroiliac joint disease, which can detect soft tissue lesions better and show low level of AS.
