Abstract

Arthritis of the sacro-iliac joints is a fairly common condition occurring either in isolation or as a part or pelvospondylitis. Because of the difficulty of establishing a diagnosis before X-ray changes have appeared, various radionuclide scanning techniques have been developed to make possible an early diagnosis. Opinions have differed as to the reliability of radionuclide methods using "bone seeking" radiopharmaceuticals. Patients with clinically and/or radiologically proven sacro-iliitis were imaged by means of 99m-Tc-EHDP. An S.I. index was calculated as the ratio of the maximum activity of the sacro-iliac joints to the minimum activity of the iliac wings. The accuracy of the method was very good, and it is recommended as a supplement to clinical examination and X-ray studies.

摘要

骶髂关节关节炎是一种相当常见的病症，可单独出现，也可作为骨盆脊椎炎的一部分出现。由于在X线改变出现之前难以确诊，因此已开发出各种放射性核素扫描技术以实现早期诊断。对于使用“亲骨性”放射性药物的放射性核素方法的可靠性，存在不同意见。对临床和/或放射学证实患有骶髂关节炎的患者使用99m锝-亚甲基二膦酸盐（99m-Tc-EHDP）进行成像。计算骶髂关节指数，即骶髂关节最大活性与髂骨翼最小活性之比。该方法的准确性非常好，建议将其作为临床检查和X线研究的补充手段。
