CT扫描联合全身骨显像对骨转移瘤的诊断分析

Diagnostic Analysis of CT Scan Combined with Whole Body Bone Imaging for Bone Metastases

目的:分析CT扫描联合全身骨显像对骨转移瘤的诊断价值。方法:回顾性收集开封市肿瘤医院2019年1—12月收治的100例恶性肿瘤患者临床资料,均采用CT联合全身骨显像检查,并于诊断结束后行病理检查,将其作为诊断结果“金标准”,观察全身骨显像联合CT影像学表现,并分析其对骨转移瘤特异度、灵敏度、阴性预测值、准确率及阳性预测值。结果:100例患者中,经病理诊断证实72例为骨转移瘤,28例为无肿瘤骨转移,CT诊断特异度均较全身骨显像高。联合诊断灵敏度较CT诊断高,且准确率、特异度较单纯全身骨显像诊断高。结论:CT扫描联合全身骨显像对骨转移瘤诊断具有较高准确性,可为临床治疗提供有效参考价值,值得在临床诊断中推广应用。

Objective: To analyze the diagnostic value of CT scanning combined with systemic bone imaging in bone metastases.Methods: The clinical data of 100 patients with malignant tumors admitted in the hospital from January to December 2019 were collected retrospectively. CT combined with whole body bone imaging was used for examination, and pathological examinations were performed after the diagnosis, which was regarded as the “gold standard” of diagnosis. Whole body bone imaging combined with CT imaging performance was observed, and its specificity, sensitivity, negative predictive value, accuracy rate, and positive predictive value for bone metastases were analyzed. Results: Among 100 patients, 72 cases were confirmed to be bone metastases by pathological diagnosis, and 28 cases had no bone metastases. The specificity of CT diagnosis was higher than that of whole body bone imaging. The sensitivity of combined diagnosis was higher than that of CT diagnosis, and the accuracy and specificity were higher than that of pure whole body bone imaging. Conclusion: CT scan combined with whole body bone imaging has high accuracy in the diagnosis of bone metastases, which can provide effective reference value for clinical treatment, and is worthy of promotion and application in clinical diagnosis.
