摘要
本研究利用放射性同位素骨三相显像技术测定并比较了１８头中国实验用小型猪和２０只恒河猴颈下颌关节区的血流，结果发现，与下颌骨不同部位相比，两种动物均显示颞下颔关节区血流相时间──放射性强度曲线峰值最高，血流到达时间最短，血地相和延迟相均显示两侧颞下颌关节区放射性强度对称，这提示颞下颌关节区具有丰富的血供而且两侧基本一致。
lood flow of the temporomandibular joint was
evaluated in 18 miniature pigs and 20rhesus monkeys by using a“three-phase technique”of
radionuclide skeletal imaging.We found that the values of the time-activity curve of blood flow
imaging in the temporo-mandibular joint Were the highest of all parts of the mandible in the
animals.Uptake ofTc-99m MDP in right and left temporomandibular joint were symmetric in the
blood poolimage and the static image . The results suggest that there is abundant blood supply
for thetemporomandibular joint,and that two side joints have identical blood flow .
