为了判断良、恶性骨肿瘤，作者利用临床流行病学方法，对42例骨肿瘤患者行彩色多普勒血流显像及病理对照研究，结果显示，彩色多普勒血流显像对良、恶性骨肿瘤的诊断灵敏度94．29％、特异度85．71％、准确度92．86％、假阳性率14．29％、假阴性率5．71％、阳性预告值97．06％、

To determine benign and malignant bone tumors, the authors used clinical epidemiological methods to perform color Doppler flow imaging and pathological control studies on 42 patients with bone tumors. The results showed that color Doppler flow imaging was good, Malignant bone tumors have a diagnostic sensitivity of 94.29%, a specificity of 85.71%, an accuracy of 92.86%, a false positive rate of 14.29%, a false negative rate of 5.71%, and a positive predictive value of 97.06%.
