对正常中国人３０髋及股骨头缺血性坏死（ＦＨＩＮ）病人３５髋进行了放射性核素因子分析显像检查，同时与单光子发射的计算机断层扫描（ＳＰＥＣＴ）、骨三相检查方法比较，并且进一步对ＦＨＩＮ手术后６个月的病人复查放射性核素因子显像。结果表明，放射性核素因子分析显像骨因子图中早期ＦＨＩＮ病人股骨头影较正常对照组明显浓聚，软组织影无明显差异，骨因子贡献率高于正常对照组（Ｐ＜０．０５）；中晚期ＦＨＩＮ病例骨因子图中股骨头影和软组织影较早期ＦＨＩＮ病例明显浓聚，骨因子、软组织因子贡献率高于早期ＦＨＩＮ病例（Ｐ＜０．０５），而血因子贡献率低于早期ＦＨＩＮ病例（Ｐ＜０．０５）。手术治疗ＦＨＩＮ６个月后复查骨因子贡献率明显低于手术前（Ｐ＜０．０５），血因子贡献率明显高于手术前（Ｐ＜０．０５）。放射性核素因子分析显像、ＳＰＥＣＴ、骨三相检查方法异常检出率早期病例分别是７６．４７％、５２．９４％、３５．２９％，晚期异常检出率均是１００％。表明放射性核素因子分析显像诊断早期股骨头缺血性坏死临床实际应用价值显著
Thirty-five hips of normal Chinese and 35 hips of patients with avascular necrosis of femoral head (FHIN) were examined by radionuclide factor analysis. Comparing with single photon emission computed tomography (SPECT) and bone three-phase examination, And further review of radionuclide factor imaging in patients 6 months after FHIN surgery. The results showed that the radionuclide factor analysis showed that the femoral head shadow of early FHIN patients was significantly concentrated compared with that of the normal control group. There was no significant difference in the soft tissue shadow between the two groups. The contribution rate of bone factor was higher than that of the normal control group (P <0.05) ; In the mid-late FHIN cases, the femoral head shadow and soft tissue shadow were significantly enriched in early FHIN cases. The contribution rate of bone factor and soft tissue factor was higher than that of early FHIN cases (P <0.05), while the contribution rate of blood factor was lower than Early FHIN cases (P <0.05). The contribution rate of bone factor after operation FHIN for 6 months was significantly lower than that before operation (P <0.05), and the contribution rate of blood factor was significantly higher than that before operation (P <0.05). Radionuclide factor analysis imaging, SPECT, bone three-phase detection of abnormal detection rate of the early cases were 76.47%, 52.94%, 35.29%, the late detection rate was 100%. Radionuclide factor analysis showed that the diagnosis of early avascular necrosis of clinical practical value of significant
