CT、ECT在脊柱关节病诊断中的价值

The value of CT and ECT in the diagnosis of spodyloarthritis

目的 探讨CT、ECT核素骨显像对脊柱关节病 (SpA)的诊断价值。 方法 对临床诊断为SpA患者 6 3例 (其中强直性脊柱炎 2 6例、未分化脊柱关节病 37例 )同时进行骶髂关节CT扫描和ECT全身及骶髂关节局部显像。结果 CT对未分化脊柱关节病检查阳性率为 2 4 3% (9/37) ,远低于ECT检查阳性率 6 4 9% (2 4 /37) ;ECT对强直性脊柱炎的诊断阳性率为 5 3 8% (14 /2 6 )。结论 ECT核素骨显像早期诊断SpA较CT敏感 。

Objective To investigate the value of CT and ECT in the diagnosis of the spodyloarthritis(SpA). Methods 63 cases of spodyloarthritis ,including 26 cases of ankylosing spondylitis(AS) and 37 cases of undifferentiated spondyloarthropathies(uSpA). The CT scan and ECT bone scintigraphic imaging were performed. Results The positive ratio of CT sacroiliac joint scan of uSpA was 24 3%(9/37), much lower than that of ECT bone scintigraphic imaging: 64 9%(24/37). The positive ratio of ECT to AS was 53 8%(14/26). Conclusion The early diagnostic value of ECT in spodyloarthritis is higher than that of CT scan.
