Abstract:
Objective To analyze and compare the independent and combined diagnostic values of high frequency ultrasonography (HFU) and molybdenum target imaging (MTI) for early breast tumor in a prospective study.Methods 258 patients with breast mass which were suspected as breast tumors by physical examination received HFU,MTI,their combined applications and operative treatments.Comparative studies were made between the surgical pathology and imaging evaluations.Results Totally 258 cases were enrolled in this study.Surgical pathology confirmed 135 cases of early breast cancer and 123 cases of benign breast tumor.For the diagnosis of early breast cancer,combined application was more effective than HFU or MTI alone in sensitivity (P<0.05),and more superior than MTI alone in accuracy.While the specificity,positive predictive value,negative predictive value, false positive rate, false negative rate had no difference among HFU, MTI and combined applications (P>0.05).In the patients of early breast cancer, compared with HFU,MTI found less nodules of calcification(18.3% vs 36.5%,P<0.01),but revealed more axillary lymph metastasis (69.0% vs 33.3%,P<0.01).Conclusion HFU and MTI alone or their combined application are reliable imaging methods for the diagnosis of early breast cancer.For the sensitivity and accuracy of diagnosis, combined applications has more superior advantages.
