摘要
目的：探讨各个年龄段正常骨显像胸骨核素分布特征。方法：120例无胸骨疼痛症状及肿瘤病史的患者作为研究对象行全身骨显像，分析其胸骨核素分布特征。结果：①儿童组胸骨核素分布特征相似，核素摄取均匀对称；其他年龄组胸骨核素分布具有异型性，可分为7种类型。②胸骨核素浓聚灶多出现在胸骨角，稀疏缺损灶出现在胸骨下端。结论：胸骨核素分布存在年龄相关的正常变异，了解这些变异有助于区分正常与异常改变。
Abstract
Objective: To describe the normal appearance of the sternal area on bone scintigraphy. Methods: 120 patients, who did not have symptoms of the sternum or a history of malignancy, underwent whole-body bone scan and were evaluated for characters of sternal uptake. Results: ①In pediatric patients, their character was similar, and sternal uptake was homogeneous. In other patients, the sternum showed markedly different, and seven different patterns of sternal uptake were noted. ②The most common hot spot was at the angle of Louis, and there was focal spot of decreased tracer uptake in the lower sternum. Conclusion: This study showed age-related normal variants of sternal uptake. Understanding these variants may be helpful in differentiating normal and abnormal patterns of uptake in the sternum on radionuclide bone imaging.
