SPECT／CT对早期疑似肿瘤骨转移灶鉴别诊澎的价值

目的 探讨SPECT/CT对早期疑似肿瘤骨转移灶鉴别诊断的临床应用价值.方法 总结在我院使用SPECT/CT诊断的疑似肿瘤骨转移灶患者90例资料（共100个病灶部位）,所有患者在使用单纯SPECT扫描无法确诊后使用SPECT/CT扫描,将诊断结果与临床病理学（或手术过程）确诊结果进行比较.结果 经过病理学（或手术过程）确诊,SPECT/CT诊断显示恶性病灶40个,良性病灶56个,无法确诊病灶3个（3.0%）,误诊病灶1个（1.0%）,诊断灵敏度95.6%,特异性93.1%,阳性预测值90.3%,阴性预测值96.5%.结论 SPECT/CT对早期疑似肿瘤骨转移灶鉴别诊断具有较高的诊断价值.

Value of SPECT/CT on differential diagnosis for early cancer bone metastasis

Objective To explore the SPECT/CT on early cancer bone metastasis differential diagnosis. Methods To summarize in our hospital using SPECT/CT diagnosis of suspected cancer bone metastases in 90 cases （100 in total lesion）, all patients in the use of pure SPECT scan could not be diagnosed after using SPECT/CT scan, finally use statistical methods to diagnosis and clinical pathology （or operation process diagnosis results）. Results After pathology （or operation process diagnosis of SPECT/CT diagnosis）, 40 benign lesions of malignant lesions, 56 benign lesions of benign lesions, cannot be diagnosed lesions were 3 （3%）, 1（1%） was misdiagnosed, diagnostic sensitivity was 95.6%, specificity was 93.1%, the positive predictive value for in 90.3%, the negative predictive value of 96.5%. Conclusion SPECT/CT for early cancer bone metastasis differential diagnosis has good diagnostic value.
