摘要 目的 评价SPECT骨显像技术观察下颌移植骨成活的价值。方法 分别于1、2、4和8周,对30例骨移植病人行⁹⁹ Tc^m -亚甲基二膦酸盐骨显像及半定量动态观察。结果 30例移植骨均成活;27例放射性摄取第1周增加,第2周最高,以后逐渐减少至正常;2例放射性摄取2周前减少,第4周增加,第8周正常;1例放射性摄取第1周减少,第2周增加,以后逐渐减少至正常。结论 放射性核素骨显像能早期判断下颌移植骨的成活情况。

Abstract Objective Tostudy the value of ⁹⁹ Tc^m -MDP bone scanning in monitoring thesurvival of mandibular bone grafts.Methods 1, 2, 4, 8 weeks after thetransplantation of mandible, the bone grafts of 30 patients were dynamically studied bythe ⁹⁹ Tc^m -MDP SPECT and semi-quantitative analysis.Results Thesurvival of mandibular bone grafts were seen in all of the 30 cases.There were threepatterns: ①In 27 cases, the radioactivity of the bone grafts increased in the firstweek, and reached the highest in the second week, then dropped gradually back to normal;②In 2 cases, the radioactivity decreased in the first two weeks, and then increased bythe 4th week, back to normal at the 8th week. ③In 1 case, decreased in the first week,increased in the second week, then gradually back to normal. Conclusions Radionuclidebone imaging was the chief method for early assessment of the survival of mandibular bonegrafts.
