目的:探讨核素骨显像骶髂关节与骶骨放射性比值测定诊断强直性脊柱炎(AS)的价值。方法:20例AS患者,共39个骶髂关节,CT检查诊断为0、Ⅰ、Ⅱ、Ⅲ、Ⅳ期骶髂关节炎。先行全身骨显像、骶髂关节显像及放射性比值测定,1~3d后行CT引导下骶髂关节穿刺活组织检查。结果:核素骶髂关节显像示放射性比值升高关节35个。20例患者均有全身其它关节或脊柱病变。活组织检查示骶髂关节炎关节38个,均有不同程度的滑膜炎、软骨及软骨下骨板血管翳侵入、骨质破坏等病变。结论:核素骨显像及其放射性比值测定有利于AS骶髂关节炎的早期诊断,对其活动性监测有临床价值。
Objective: To investigate the value of radionuclide scintigraphy in the diagnosis of ankylosing spondylitis (AS) with the ratio of sacroiliac joint and sacrum radioactivity. Methods: Twenty-nine patients with AS and 39 sacroiliac joints were diagnosed as CT. CT sacroiliac joints were diagnosed as 0, Ⅰ, Ⅱ, Ⅲ and Ⅳ. The first whole body bone imaging, sacroiliac joint imaging and radioactive ratio determination, 1 ~ 3d after CT-guided sacroiliac joint biopsy. Results: Nuclide sacroiliac joint imaging showed that radioactive ratio increased 35 joints. All 20 patients had other systemic or spine lesions. Biopsy showed sacroiliitis joint 38, have varying degrees of synovitis, cartilage and subchondral bone vascular invasion, bone destruction and other diseases. Conclusion: Radionuclide bone imaging and radioactive ratio determination are beneficial to the early diagnosis of sacroiliac arthritis, and have clinical value for monitoring their mobility.
