近10年来,恶性肿瘤骨闪烁照相的应用业已扩大,它在发现转移性病变、监测治疗效果及早期发现复发均占有重要地位。本文报告1974～1982年三种常见原发性恶性骨肿瘤作骨闪烁照相研究的经验,目的在于分析它们各自的显象特点,试图提出明确的诊断,从而促进正确处理。方法:注入~(99m)Tc焦磷酸盐(350μCi/kg),用一大视野γ照相机作为闪烁照相。某些病人在注入放射性核素后还作即刻的血池显象,但在2～4小时均作全身扫描,有任何异常区亦作局部观察。根据闪烁照相图特征分为四个等级:(1)肿瘤浓聚放射性的强度;(2)放射性分布的类型;(3)骨外形改变;(4)病灶边缘闪烁图象。每个等级中根据程度不同
In the past 10 years, the use of bone scintigraphy for malignant tumors has expanded, and it has played an important role in the detection of metastatic lesions, monitoring of treatment effects, and early detection of recurrence. This article reports the experience of three common primary malignant bone tumors from 1974 to 1982 for bone scintigraphy studies. The purpose is to analyze their respective imaging features and attempt to provide a clear diagnosis to promote proper treatment. METHODS: ~(99m)Tc pyrophosphate (350 [mu]Ci/kg) was injected and scintigraphy was performed with a large field gamma camera. Some patients also performed immediate blood pool imaging after injecting radionuclides, but whole body scans were performed in 2 to 4 hours, and any abnormal areas were also observed locally. According to scintigraphy features are divided into four levels: (1) intensity of tumor-enriched radioactivity; (2) type of radioactivity distribution; (3) change in bone profile; (4) scintigraphy of lesion edges. Different levels in each level
