目的 研究CT和发射型计算机断 层成像(ECT)在骨转移瘤诊断中的应用效 果比较。方法 选择医院2015年12月到 2017年12月恶性肿瘤患者共100例，所有 患者均进行CT、ECT检查。统计两种检测 方式诊断骨转移瘤的效能，包括准确率、 特异性、敏感性；统计两种检测方式对不 同恶性肿瘤检出率；统计两种检测方式对 不同病灶部位判断的准确率。结果 ECT诊 断骨转移瘤准确率高于CT，差异有统计学 意义(P＜0.05)；ECT诊断骨转移瘤灵敏 性、特异性均高于CT检测，但差异无统计 学意义(P＞0.05)；ECT对不同恶性肿瘤检 出率高于CT，但差异无统计学意义(P＞ 0.05)；ECT判断不同病灶部位的准确率均 高于CT检测，但差异无统计学意义(P＞ 0.05)。结论 ECT在诊断骨转移瘤的准确 性上高于CT检测。

Objective To study and compare the effects of CT and emission computed tomography (ECT) in the diagnosis of bone metastases. Methods A total of 100 cases of patients with malignant tumors from December 2015 to December 2017 were selected. All patients were given CT and ECT examinations. The efficacy of two detection methods was counted in diagnosing bone metastases, including accuracy, specificity and sensitivity. The detection rate of the two detection methods were counted in detecting different malignant tumors. The accuracy of the two detection methods in judging different lesions sites was statistically determined. Results The accuracy of ECT was higher than that of CT in the diagnosis of bone metastases (P<0.05). The sensitivity and specificity of ECT in the diagnosis of bone metastases were higher than those of CT (P>0.05). The detection rate of different malignant tumors by ECT was higher than that by CT (P>0.05). The accuracy of judging different lesions sites by ECT was higher than that by CT (P>0.05 ). Conclusion ECT has higher accuracy than CT in the diagnosis of bone metastases.
