用133Xe清除法测量了18名正常人、8例股骨头坏死和7例股骨颈处骨折病人股骨颈局部血流灌注，并就骨坏死（或骨折）病人与正常人股骨颈局部血流灌注进行了分析比较，以研究骨病变后血流灌注的变化。结果表明，正常成年人股骨颈局部血流灌注均值为7．22±0．53mL／（100g·min）；8例股骨头坏死病人的坏死侧与正常人股骨颈局部血流灌注均值之间存在显著性差异（t＝6．028，P＜0．001），坏死侧血流灌注要低于正常侧。股骨颈处骨折术后，其双侧股骨颈局部血流灌注未见有显著性差异（t＝1．357，P＞0．20）。
Eighteen normal subjects, eight femoral head necrosis patients and seven patients with femoral neck fracture underwent local perfusion of the femoral neck with 133Xe clearance method. Local perfusion of the femoral neck of patients with osteonecrosis (or fracture) and normal subjects Analysis and comparison to study changes in blood flow perfusion after bone lesions. The results showed that the mean femoral neck partial perfusion of normal adults was 7.22 ± 0.53mL / (100g · min). There was a significant difference between the mean femoral neck partial perfusion of 8 patients with necrosis of femoral head and normal femoral neck Significant difference (t = 6.028, P <0.001), necrosis side of blood perfusion was lower than the normal side. Femoral neck fractures, the bilateral femoral neck local blood flow perfusion showed no significant difference (t = 1.357, P> 0.20).
