99m-Tc--polyphosphate bone imaging was useful in distinguishing Legg-Perthes disease from other childhood hip disorders in 40 patients. In 33 Legg-Perthes patients, imaging provided earlier and more accurate information concerning the extent of the necrotic and revascularization process involving the hip than radiographs alone. This advantage could both facilitate treatment selection and provide a more objective baseline from which to judge treatment results. Preliminary experience also suggests that the technique may offer some insight into the pathogenesis of Legg-Perthes disease.
99m锝-多聚磷酸盐骨显像有助于鉴别40例儿童Legg-Perthes病与其他儿童髋关节疾病。在33例Legg-Perthes病患者中，与单纯X线片相比，骨显像能更早、更准确地提供有关髋关节坏死及血管再生过程范围的信息。这一优势既能有助于治疗方案的选择，又能提供一个更客观的基线来判断治疗效果。初步经验还表明，该技术可能有助于深入了解Legg-Perthes病的发病机制。
