Differential diagnosis value of benign and malignant breast nodules by color Doppler flow imaging combined with ultrasonic elastography
Objective To investigate the differential diagnosis value of color Doppler flow imaging(CDFI)com-bined with ultrasound elastography(UE)examination in the benign and malignant breast nodules.Method A total of 80 breast nodules patients(92 nodules)were examined by CDFI and UE.The result of pathological examination was used as the"gold standard"to analyze the differential diagnostic efficacy of CDFI and UE alone and combined examination in be-nign and malignant breast nodules.Result The accuracy,specificity and sensitivity of CDFI examination in the diagno-sis of malignant breast nodules were 78.26%(72/92),77.78%(42/54)and 78.95%(30/38),respectively.The accuracy,specificity and sensitivity of UE in the diagnosis of malignant breast nodules were 76.09%(70/92),88.89%(48/54)and 57.89%(22/38).The accuracy,specificity and sensitivity of CDFI combined with UE examination in the diagnosis of ma-lignant breast nodules were 91.30%(84/92),88.89%(48/54)and 94.74%(36/38).The sensitivity and accuracy of CDFI combined with UE examination in the diagnosis of malignant breast nodules were higher than those of UE and CDFI alone examination.Conclusion CDFI combined with UE examination has higher differential diagnostic efficiency for benign and malignant breast nodules,which is more advantageous than single diagnosis.
