Diagnostic Value Study Of ABVS Compared With MG And HHUS In Breast Masses

Objective: Calculate the sensitivity, specificity, accuracy, positive predictive value, negative predictive value and accuracy rate of Automated breast volume scanner(ABVS) in diagnosis of breast masses.And the hand-held ultrasound and mammography were compared with to explore the value of ABVS in diagnosis of breast masses and its clinical application value.Material and Methods: 71 female patients with 71 breast masses in our hospital from August 2014 to February 2015 were retrospectively analyzed.Patients age 28~77 years old, average age(43.68 + 9.56) years old.All patients underwent ABVS, HHUS and MG these three examinations.All imaging data of ABVS, hand-held ultrasound and mammography were shared by 2 physicians with more than 5 years of experience in the diagnosis of breast diseases.The diagnostic criteria of lesions was the Radiological Society of North America and breast imaging reporting and data system(BI-RADS) classification standard. II-IV(4a) were classified as benign lesions, IV(4b)-V level were classified as malignant lesions. All 71 cases were confirmed by surgery or biopsy.Calculate AVBS, hand-held ultrasound and mammography in diagnosis of breast masses of sensitivity, specificity, accuracy, positive predictive value, negative predictive value and the infiltration ductal cancer, intraductal carcinoma, fibroadenoma and breast adenosis diagnostic accordance rate.The difference between them were analyzed by application of SPSS17.0 statistical software using chi square test.To P < 0.05, the difference was statistically significant.Result: The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ABVS in the diagnosis of breast masses were 93.33%, 90.24%, 91.55%, 87.50%, 94.87% and ABVS’s diagnosis coincidence rate of infiltration ductal cancer, intraductal carcinoma, fibroadenoma and breast adenosis were 95.8%, 83.3%, 96.2%, 78.6%. ABVS detected out all the 71 breast masses.About mammography, the sensitivity, specificity and accuracy were 83.33%, 73.17%, 77.46%, the positive predictive and negative predictive values were 92.59% and 93.75% in the diagnosis of breast masses, and the coincidence rate of mammography in the diagnosis of infiltration ductal cancer, intraductal carcinoma, fibroadenoma and breast adenosis were 83.3%, 83.3%, 81.5%, 57.1%. In the diagnostic specificity and accuracy and the diagnosis of fibroadenoma and breast adenosis coincidence rate, ABVS was significantly higher than that in breast molybdenum target, the difference is statistically significant(P < 0.05). At the same time, a total of 59 breast lesions were detected by mammography, and the detection rate of the lesions was lower than that of ABVS, the difference is statistically significant(P < 0.05). The hand-held ultrasound in the diagnosis of breast mass sensitivity, specificity, accuracy, positive predictive value, negative predictive value were 83.33%, 82.92%, 83.10%, 78.13%, 87.18%, and it’s diagnosis coincidence rate of infiltration ductal cancer, intraductal carcinoma, fibroadenoma and breast adenosis were 87.5%, 66.7%, 92.6% and 64.3%. In the above aspects, there was no significant difference between ABVS and hand-held ultrasound.Conclusion: Automated breast volume scanner has high sensitivity, specificity, accuracy, positive predictive value, negative predictive value and diagnostic accuracy in the diagnosis of breast masses.There was no significant difference between ABVS and hand held ultrasound and it was significantly better than those of mammography in the specificity, accuracy and so on.ABVS has a high diagnostic efficiency for breast lumps and reflected good clinical application value.
