【摘要】 目的强直性脊柱炎骶骼关节病变采用MRI与CT两种不同方式进行诊断,比较两种诊断方法的临床应用价值,以为临床诊断及治疗方案选择提供有力参考依据。方法选取本院所收治的78例强直性脊柱炎患者作为本次研究对象,并分别采用MRI与CT对患者进行检查,同时根据本次所检查结果来对其临床病变情况进行判断和比较。观察2组患者临床诊断情况,并比较2者间所检出骨质异常情况,加以分析。结果经检查发现,MRI检出骨质异常率明显低于CT检出率(P<0.05)。然CT检查I级强直性脊柱炎骶骼病变敏感性为17.95%(14/78)明显低于MRI检查敏感性为33.33%(26/78)(P<0.05);而对于II级以上病变检出情况,2者比较无统计学意义(P>0.05)。结论相比MRI诊断来说,临床采用CT扫描检查诊断强直性脊柱炎骶骼关节病变具有更高的空间分辨率,因此可有效提高临床疾病诊断率,从而更好地为临床判断强直性骶骼关节病变提供参考价值。然临床采用MRI用于诊断强直性骶骼关节病变,其可较好地将患者脂肪沉积、关节软骨等病变清晰显示,从而有利于微小疾病发现。所以,MRI检查一般用于检测早期强直性脊柱炎骶骼关节病变。更多还原

【Abstract】 Objective Ankylosing spondylitis sacroiliac joint disease using MRI and CT diagnosis in two different ways, the clinical value comparison of two diagnostic methods, that the clinical diagnosis and treatment options provide a strong reference. Methods Select this institute admitted 78 cases of patients with ankylosing spondylitis as the object of this study, and were used MRI and CT examination of the patient, but to judge and compare the clinical lesions examined in accordance with this outcome. Observed two groups of patients clinically diagnosed cases and compared between the two bone abnormalities detected by those who, to be analyzed. Results The inspection found that, MRI detected bone abnormalities was significantly lower than CT detection rate(P<0.05). However, CT examination stage I disease ankylosing spondylitis sacroiliac sensitivity of 17.95%(14/78) was significantly lower than the sensitivity of MRI examination was 33.33%(26/78)(P<0.05); and for detecting lesions above the level II the case, two were not statistically significant(P>0.05). Conclusion Compared to MRI diagnosis, the clinical use of CT scanning in the diagnosis of ankylosing spondylitis sacroiliac joint disease has a higher spatial resolution, it can effectively improve the clinical diagnosis rate, thus better for the clinical judgment of ankylosing sacroiliac joint lesions provide a reference value. However, the clinical use of MRI for the diagnosis of ankylosing sacroiliac joint disease, it may be better to be fat deposition in patients with articular cartilage lesions clear display, which found in favor of minor illness. Therefore, MRI examination is generally used to detect early ankylosing spondylitis sacroiliac joint disease.更多还原
