| 摘 要： | 骨骼是恶性肿瘤常见的转移部位之一，骨转移常常与疾病的预后紧密相关，因而放射性核素骨显像在肿瘤骨转移的诊断中具有举足轻重的作用。平面骨显像凭借着其反映骨骼病变的高灵敏度广泛应用于临床，且具有检查费用较低、可反映骨代谢血流及不受金属置入物影响等优点。较之平面骨显像，SPECT/CT骨断层显像可以更好地定位病变，对病变的检出率更高且诊断的特异性更强。该文对SPECT/CT骨断层显像及其在诊断恶性肿瘤骨转移中的临床价值进行综述。

| Abstract: | Bone is one of the most favorite sites of malignant tumor metastasis,and bone metastasis usually correlates with the prognosis of disease,which leads to the important place of bone scintigraphy in the diagnosis of bone metastasis.Bone scan is widely used in clinical work for its high sensitivity as well as its low cost,revealing bone metabolism and blood flow,and no limitation of metal implantation.Compared with plain bone scan,SPECT/CT bone tomography shows better orientation of lesion,and has higher detection rates and specificity.This article reviews the diagnostic value of malignant tumor bone metastasis. |
