Abstract
Objective:To analyze the value of pulsed-wave Doppler(PW)ultrasound and ultrasonic elastography in the differential diagnosis of benign and malignant breast masses.Method:A total of 81 patients with breast masses who admitted to the Fourth People's Hospital of Langfang from February 2021 to March 2023 were selected as the research objects,all patients were underwent ultrasonic elastography and PW ultrasound examination,the pathological results of 81 patients with breast masses were counted,the results of ultrasonic elastography scores of benign and malignant masses were compared,the results of postoperative pathological examination were used as the gold standard to analyze the clinical value of ultrasonic elastography and PW ultrasound in the diagnosis of benign and malignant breast masses.Result:Among 81 patients,30 cases were malignant,including 26 cases of invasive carcinoma,2 cases of ductal carcinoma,1 case of carcinoma in situ,and 1 case of mucinous carcinoma;51 cases were benign,including 30 cases of breast fibroadenoma,9 cases of intraductal papilloma,7 cases of fibrocystic breast disease and 5 cases of epidermoid cyst.The proportion of 4-5 points of ultrasonic elastography in malignant breast masses was higher than that in benign breast masses,and the difference was statistically significant(P<0.05).With the results of pathological examination as the gold standard,a 2×2 four-fold table was drawn with PW ultrasound and ultrasonic elastography respectively,PW ultrasound detected 25 cases of true malignancy and 45 cases of true benignity;ultrasonic elastography detected 24 cases of true malignancy and 47 cases of true benignity.The sensitivity of PW ultrasound in the diagnosis of malignant breast masses was 83.33%,the specificity was 88.24%,the accuracy was 86.42%,the missed diagnosis rate was 16.67%,and the misdiagnosis rate was 11.76%;the sensitivity of ultrasonic elastography in the diagnosis of malignant breast masses was 80.00%,the specificity was 92.16%,the accuracy was 87.65%,the missed diagnosis rate was 20.00%,and the misdiagnosis rate was 7.84%;the sensitivity of ultrasonic elastography combined with PW ultrasound in the diagnosis of malignant breast masses was 93.33%,the specificity was 94.12%,the accuracy was 93.83%,the missed diagnosis rate was 6.67%,and the misdiagnosis rate was 5.88%.Conclusion:PW ultrasound and ultrasonic elastography can provide a reliable reference for the differential diagnosis of benign and malignant breast masses.关键词
