^(133)Xe清除法测量人股骨颈局部血流灌注

Measurement of human regional blood flow of femur neck with ^(133)Xe Washout method

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）。

Regional blood flow (rBF) of femur neck in 18 normal people, 8 arascular necroisof femur neck (AVNFN) patients and 7 fracture of femur neck (FFN) patients weremeasured with 133Xe washout method. The results showed that the average rBF offemtir neck in normal people, the AVNFN patients and the FFN patients are 7.22±0.53, 5.39± 1.48 and 6.74± 1.63 mL/(100g·min) respectively. The rBF of AVNFNpatients was lower than that of normal people (t = 6.028, P<0.001); whereas the rBFof fracture patients was not statistically different from that of the normal people(t = 1.357, P>0.20).
