摘　　要：目的分析乳腺癌放疗致肋骨骨折的骨显像增高灶的形态、位置、出现和消失时间及X线表现。方法回顾分析18例诊断为放疗后肋骨骨折的乳腺癌患者的骨显像系列片。结果该组增高灶表现为类圆形或椭圆形,多为轻、中度放射性摄取,多发者线性排列,位于第3～7肋腋前线上或第2肋中部。增高灶出现距离放疗结束的时间为9至39个月。X线示相应肋骨局部骨质密度增高、骨痂形成或断裂不愈合。结论根据肋骨增高灶的形态、位置、与放疗的时间关系及X线表现有助于与骨转移鉴别。Objective To analyze the performance, position and the time of appearance and disappearance of radiation damage of ribs on bone scan in patients with breast cancer after radiotherapy. Methods A series of bone scans of eighteen patients with breast cancer after radiotherapy and have high uptake lesions in the ribs in the radiation fields diagnosed as fracture were analyzed. Results All of the lesions were manifested as rounded, mild or moderate radio uptake lesion. They were arrayed on a line when several ribs involved. The high uptake lesions appears on the prior line of axilla on 3rd to 7th ribs or on the middle of the second ribs. The time interval between the end of radiotherapy and the appearance of the high radio uptake lesions on the bone scans is 9 to 39 months. The high radio uptake lesions show high density lesions or healed or not healed fractures on the same areas on X-rays. Conclusion The performance, position, the time of appearance of high uptake lesions on bone scan, and combining the chest X-ray can help us to differentiate radiation damages from bone metastasis.
