摘要
对１０例（２０个髋）正常人和２８例（３５个髋）成人股骨头缺血性坏死（ＡＦＨＩＮ）病人进行了放射性核素显像因子分析，并与骨ＳＰＥＣＴ显像和骨三时相显像进行了对比．结果表明ＡＦＨＩＮ病人病变股骨头的骨因子图像表现为明显浓聚，随病情加重股骨头影像增大，且逐渐增浓．Ⅰ、Ⅱ期ＡＦＨＩＮ病人软组织因子图像无异常，Ⅲ期以上者的软组织因子图像可见髋关节处有明显浓聚．对Ⅰ、Ⅱ期ＡＦＨＩＮ病人诊断的灵敏度以因子分析图像最高，为７６．４７％．ＳＰＥＣＴ为５２．９４％，骨三时相显像为３５．２９％．而三者对Ⅲ期以上ＡＦＨＩＮ的灵敏度基本一致．故放射性核素显像因子分析不但可以早期诊断ＡＦＨＩＮ，而且对该病的分期判定也有重要的临床应用价值．
Abstract health adults(20 hips)and 28 adult patients with femoral head ischemic necrosis (AFHIN) (35hips) were examined by factor analysis of radionuclide imaging and compared with bone SPECT and 3-phase bone imaging.The results showed that there is increased accumulation in the lesion hip joint in patients with early AFHIN(Ⅰand Ⅱ stage)on bone factor image only.In the patients with late AFHIN(>Ⅲ stage),marked accumulation appeared not only on the bone factor image but also on the soft tissue factor analysis image.For detecting early AFHIN,the sensitivity of factor analysis image is 76.47%,bone SPECT 52.94% and 3-phase bone image 35.29%,but for late AFHIN the sensitivity of the three methods is almost same.In conclusion, radionuclide factor analysis imaging was useful for early diagnosis of A FHIN.
