介入性超声诊断后方衰减在乳腺肿瘤中的应用价值

Diagnosis Value of Interventional Ultrasound in Breast Cancer Rear Attenuation

目的探讨介入性超声诊断后方衰减在乳腺肿瘤中的应用价值,以期为乳腺肿瘤的诊断方法的选择提供参考。方法选取70例有后方衰减的乳腺肿瘤患者,行彩色多普勒超声检查、介入性超声检查,与手术病理结果进行对照分析。结果彩色多普勒超声检查诊断为恶性29例,良性41例;介入性超声检查诊断为恶性33例,良性37例;病理金标准结果恶性39例,良性31例。采用超声多普勒超声检查,诊断恶性肿瘤的灵敏度为56.4%(22/39),阳性预测值为75.9%(22/29),特异度为77.4%(24/31);介入性超声检查恶性肿瘤灵敏度为91.4%(32/39),阳性预测值为97.0%(32/33),特异度为97.1%(34/35)。结论介入性超声对存在后方衰减的乳腺肿瘤能提高对良、恶性肿瘤的鉴别诊断灵敏度、特异度及诊断符合率。

Objective To investigate the diagnosis value of interventional ultrasound in breast tumor with rear attenuation, in order to provide reference for the choice of method for the diagnosis of breast tumor. Methods A total of 70 cases of breast cancer with rear attenuation were included in the study, color Doppler ultrasound and interventional ultrasound examination were done, and were comparatively analyzed with surgi- cal pathological results. Results Color Doppler ultrasound diagnosis results ： malignant 29 cases, benign 41 cases ;interventional ultrasound diagnosis results ： malignant 33 cases, benign 37 cases; pathological gold standard results ： malignant 39 cases, benign 31 cases. Color Doppler ultrasound examination ： the sensitivity of diagnosis of malignant tumors was 56. 4% （22/39）, positive predictive value was 75.9% （22/29）, speci- ficity was 77.4% （24/31） ; interventional ultrasound inspection： the sensitivity of diagnosis of malignant tumors was 91.4% （32/39）, positive predictive value was 97.0% （32/33）, specificity was 97.1% （34/ 35）. Conclusion Interventional ultrasound can improve the sensitivity, specificity and diagnostic coinci- dence rate of differential diagnosis of benign and malignant tumors of breast tumor with rear attenuation.
