Objective:To analyze the clinical value of CEUS in the differential diagnosis of benign and malignant breast masses.Methods:70 patients with breast masses admitted to the hospital from May 2021 to August 2023 were selected as the research subjects,and they were subjected to X-ray molybdenum target,contrast-enhanced ultrasound,and surgical pathological examination.Using postoperative pathological examination results as the diagnostic gold standard,observe the results of differential diagnosis between benign and malignant breast masses,compare the sensitivity,specificity,and accuracy of X-ray molybdenum target and contrast-enhanced ultrasound differential diagnosis,and compare the ultrasound contrast imaging characteristics and quantitative indicators of patients with benign and malignant breast masses.Results:The positive predictive value,negative predictive value,sensitivity,specificity and accuracy of benign and malignant breast mass by contrast ultrasound imaging were higher than those of X-ray molybdenum target(P<0.05).The proportion of imaging features such as irregular morphology,blurred boundary,penetrating or distorting blood vessels,uneven contrast agent,filling defects,and enlarged focal lesions was higher than that of patients with benign breast masses(P<0.05).The peak intensity,area under curve and gradient were greater than those with benign masses,and the peak time was shorter than that(P<0.05);The ascending branch slope was almost consistent in both groups(P>0.05).Conclusion:CEUS can accurately identify benign and malignant breast masses,and qualitative and quantitative evaluation can predict the degree of breast mass lesions.
