An attempt has been made to improve diagnostic precision in a group of diseases associated with inflammation of the sacroiliac joints by using a 99mtechnetium stannous pyrophosphate bone scan. Inflammation of these joints is associated with osteoblastic activity and is reflected by an increase in the uptake of radionuclide, which can be precisely quantitated. The uptake was markedly above the range of normal in patients with active ankylosing spondylitis (AS), and also in a number of patients with possible AS, psoriasis, and Reiter's syndrome. However, patients with Grade 4 radiological changes of the sacroiliac joints frequently had normal scans. This technique may be useful in the early diagnosis of sacroiliitis, and the nosological implications of the changes in patients with Reiter's syndrome and psoriasis are of interest.
通过使用99m锝焦磷酸亚锡骨扫描，已尝试提高一组与骶髂关节炎症相关疾病的诊断准确性。这些关节的炎症与成骨细胞活性相关，并通过放射性核素摄取增加得以体现，而这一摄取增加量可被精确量化。在活动性强直性脊柱炎（AS）患者以及一些可能患有AS、银屑病和赖特综合征的患者中，摄取量明显高于正常范围。然而，骶髂关节有4级放射学改变的患者扫描结果常常正常。这项技术可能有助于骶髂关节炎的早期诊断，并且赖特综合征和银屑病患者的改变在疾病分类学上的意义也值得关注。
