全身核素骨显像检查软组织异常显影的结果分析

目的对全身核素骨显像时骨外软组织异常显影的规律和原因进行分析。方法通过对5248例Tc—MDP骨显像检查结果分析，特别是骨外软组织异常显影的患者进行分析，从性别、年龄、部位、器官等方面进行分类，探讨骨外软组织显影的差异性。结果在选取的骨显像检查病例中，显像异常的骨外组织显像占到总数的4％，共232例，其中82％异常核素显影病灶经过组织病理学和临床诊断后确定为恶性肿瘤，主要分布在乳腺、肺、肝部。恶性肿瘤的病灶显影为87％。骨外软组织异常核素摄取显影的病例按照年龄、性别、分布部位、显影级别等进行了分组x2比较及检验，差异均无显著性（P〉0．05）。结论通过，smTc—MDP骨显像检查出的骨外软组织摄取显影病灶主要分布于乳腺、肝脏、肺部等区域，以原发性或者转移性恶性肿瘤居多，良性病变为少数，可在综合检主或者临床进行进一步的判断。

Objective; To analyze the regularity and cause of abnormality development of extra--osseous soft tissue. Methods： Fifty--two patients with abnormal bone and soft tissue were analyzed by 99mTc--MDP bone scintigraphy. The differences of sex, age, location, and organ were analyzed, and the differences of soft tissue imaging were analyzed. Results： Among the cases of bone scan, the abnormal imaging of extracranial tissue accounted for 4% of the total, 232 cases, of which 82% of abnormalnuclide imaging lesions of tibial histopathology and clinical diagnosis was identified as Malignant tumors, mainly in the milk, lung, liver. Malignant tumor imaging lesions were 87% nuclide. There were no significant differences in the radionuclide uptake and development of extramedullary soft tissue abnormalities in malignancy according to the age, sex, distribution, and imaging agent （P〈0.05）. Conclusion.. After 99mTc--MDP examination, the extracranial soft tissue with bone imaging is mainly distribu- ted in mammary gland, liver, lung and other areas. Themajority of benign or metastatic malignancies are benign lesions, Can be carried out in the comprehensive examina- tion or clinical further judgment.
