摘　　要：目的:探讨骨外组织摄取99Tcm-MDP的临床意义。材料和方法:回顾性分析6602例99Tcm-MDP骨显像并识别骨外组织显影。结果:骨外组织显影497例。弥漫性摄取见于四肢、胸、腹部(淋巴和B或静脉回流障碍120例,恶性胸、腹腔积液各146及44例,甲状旁腺功能亢进3例,肝脏转移瘤20例);局灶性摄取见于不同部位多种类型的肿瘤(107例,除1例良性外其余均为恶性),心肌炎及脑梗死灶各1例、横纹肌炎症1例、近期骨折或手术后局部软组织各16及18例,术后瘢痕7例、术后造瘘13例。上述显影的骨外组织良性病变占33%,恶性病变占67%。结论:正确识别核素骨显像的骨外组织显影有助于对骨显像的正确分析并可提供有价值的信息。Objective： To evaluate the clinical significance of ^99Tc^m-MDP accumulation in non-osseous tissue. Materials and Methods： 6602 ^99Tc^m-MDP bone scans were reviewed and ^99Tc^m-MDP accumulations in non-osseous tissue were distinguished. Results：^99Tc^m-MDP accumulations were detected in 497 bone scans. Diffuse accumulations were detected in limbs, chest and abdomen （malignant pleural effusion, 146, malignant seroperitoneum, 44, obstruction in circumfluence of vein or lymph, 120, hyperparathyroidism, 3, metastatic tumor in liver, 20）. Regional accumulations were detected in various tumors of defferent locations（107 cases, I was benign and the others were malignant）, myocarditis（1）, infarct in brain（1）, rbabdomyositis （1）, regional soft tissue after bone fracture（16） and recent operation（18）, scar in skin（7） and stoma caused by operation（13）. In all the lesions above, benign lesions were 33% while malignant lesions 67%. Conclusion： To distinguish the ^99Tc^m-MDP accumulation in non-osseous tissue is helpful to the analysis of bone scan and can offer some valuable infoimation.
