摘要
目的 探讨骶髂关节 /骶骨放射性比值对未分化脊柱关节病 (uSpA)的诊断价值。方法对临床有腰腿症状、类风湿因子 (RF)阴性、骶髂关节X线和CT检查可疑的 76例不同年龄受检者的15 2个关节 ,进行SPECT全身骨显像及骶髂关节局部显像 ,取得不同部位的两组放射性比值 ,并与正常值比较。结果 76例uSpA患者 15 2个骶髂关节中X线平片有 16个异常 ,CT检查有 41个异常 ,骨显像有 94个骶髂关节 /骶骨放射性比值升高 ,39例患者有髋关节和 (或 )胸锁关节、腰椎等其他关节病变 ,无异常发现 19例。
Objective To evaluate characteristics of sacroiliitis on bone scintigraphy and to compare the bone scintigraphic images with findings obtained by conventional radiography and CT in patients with undifferentiated spondyloarthropathy (uSpA). Methods Seventy six uSpA patients were recruited.In each patient the conventional radiography,CT and bone scintigraphic imaging were completed within a week. SPECT was performed on whole body skeleton as well as sacroiliac joint to measure the radioactivity ratio in this joint. Results Among 152 sacroiliac joints with uSpA,the abnormal findings with conventional radiography were 16 (10.53%), with CT were 41 (26.97%), and bone scintigraphic imaging were 94 (61.84%) including metabolic changes of other joints such as hip joint,knee joint etc in 39 patients. Conclusion Comparing with conventional radiography and CT the bone scintigraphic imaging is more sensitive in detecting uSpA.
