ABSTRACT
Objective To compare the diagnostic value of high frequency ultrasound,mammography and breast blood-oxygen function imaging system in diagnosis of breast masses.Methods The images of 89 breast masses by high frequency ultrasound,mammography and breast blood-oxygen function imaging system were reviewed.The study compared the sensibilities and specificities of the three methods in the masses and analyzed their cause of missed diagnosis.Results The sensitivity of the diagnosis of breast cancer by high frequency ultrasound,mammography and breast blood-oxygen function imaging system were 80.00%,70.00% and 50.00%,respectively.The specificity of the diagnosis of breast cancer by them were 94.94%,98.73% and 97.47%,respectively.There were sigmfiacant differences in diagnosis of breast benign lesion among the high frequency ultrasound,mammography and breast blood-oxygen function imaging system.The sensitivity of high frequency ultrasound in detecting fibroadenoma of breast was 98.11% higher than the other methods.Mammography was insensitive to the benign breast lesions,but its specificity was high.Conclusions High frequency ultrasound,mammography and breast blood-oxygen function imaging system are the highly effective diagnostic tool for breast cancer,but the diagnostic value of mammography and breast blood-oxygen in breast fibroadenoma and in cystic disease of breast aren' t high.Breast blood-oxygen function imaging system can enhance the accuracy of the diagnosis of mammary inflammation.
ABSTRACT
Objective To evaluate needle localized operation biopsy (NLOB) and sterotactic core needle biopsy (SCNB) in the differential diagnosis of nonpalpable breast lesion (NPBL) found by mammography. MethodsIn 82 cases, a total of 90 NPBL were found, NLOB or SCNB were applied to make the diagnosis.ResultsBreast carcinoma (24.4%)was finally diagnosed in 20 cases, 61 cases were diagnosed with benign lesion. Thirty-five cases needed (42.7%) a surgery. Conclusion NLOB and SCNB provide new ways in establishing diagnosis of breast minimal lesions.
