摘要
目的探讨ＣＤＦＩ技术检查在骨肿瘤的应用价值，旨在对ＣＤＦＩ诊断良、恶性骨肿瘤作出客观评估。方法对４２例骨肿瘤患者行彩色多普勒血流显像研究，测量肿瘤周边及中心部血流参数。结果肿瘤周边部血流速度高于中心部血流，而ＲＩ、ＰＩ周边部低于中心部。恶性骨肿瘤血流速度高于良性骨肿瘤，而ＲＩ、ＰＩ前者低于后者，其对良、恶性骨肿瘤诊断的灵敏度９４２９％、特异度８５７１％、准确度９２８６％。
Purpose To distinguish diagnostic value of CDFI in bone tumor.Methods 42 patients
were examined by CDFI and confirmed by pathology.Results The flow velocity in the periphery
of the lesion was higher than that in the centry of the lesion.The resistance index (RI) and the
pulsatility index (PI) in the periphery were lower than those in the centry.The peak flow velocity
in maliguant was higher than that in benign.But the resistance index (RI) and the pulsatility
index (PI) in maliguant were lower than those in benign.Sensitivity 94.29%,specificity 85.71%
and accuracy 92.86%.Conclusion The color Doppler flow imaging is a useful,specifical and
helpful method in the diagnosis of bone tumors. [
