摘要放射性核素骨显像是诊断骨和软组织感染的选择性检查方法,不但有助于隐匿性骨折(X射线诊断阴性)的诊断,在评定小儿可疑非意外损伤方面起重要的补充作用,还可为无法解释的小儿骨痛或跛行提供诸如外伤、肿瘤、或炎症性病变的诊断依据.小儿核素骨显像要求精确的操作才能获得较清晰的诊断图像,常规全身骨显像、缩放比例、附加视图及单光子发射型计算机体层摄影术的使用等都是小儿检查的常规内容,联合CT的融合图像更进一步提高诊断的灵敏度、可信度和精确度.新的放射性药物如Na18F可能在不断更新变化的儿科骨显像技术中起重要作用.

abstractsRadionuclide bone imaging is used as the diagnostic procedure of choice for diagnosis of bone and soft-tissue infection and can aid in the diagnosis of occult trauma without radiographic findings.There is a complimentary role in the assessment of a child with suspected non accidental injury.It also may provide a diagnosis that could be related to trauma,tumor,or inflammation in a child with unexplained bone pain or limp.Radionuclide bone imaging in children require careful attention to technique to obtain high quality diagnostic images.Routine whole-body imaging,magnification,additional views,and the use of single-photon emission computed tomography also are a routine part of this examination in children.Correlation with conventional radiographs is mandatory,and the judicious use of hybrid imaging with the addition of computed tomography may further improve diagnostic acumen,confidence and accuracy.New radiopharmaceuticals such as Na18F may also play a role in changing techniques for pediatric radionuclide bone imaging
