Objective:To evaluate the significance of the differential diagnosis of ultrasonographic and 99mTC-tetrofosmin in breast tumor.Methods:In 64 cases with breast lesions underwent both ultrasonography and 99mTC-tetrofosmin,all patients had histopathological confirmation of the nature of the breast lesions,of them 34 were malignant and 30 were benign.Results:Ultrasonography was positive in 36 patients(30 true positive,6 false positive)and negative in 28 patients(24 true negative,4 false negative)the corresponding values of 99mTC-tetrofosmin were 36(29,7)and 28(23,5).The sensitivity of ultrosonography was 88.24%,the specificity was 80.00%,the accuracy was 84.38% and the positive and negative predictive value were 83.33% and 85.71% The corresponding values for 99mTC-tetrofosmin were 85.29%,76.67%,81.25%,80.56%,82.14%.Conclusion:Utrasonography are still the commonly used methods to diagnose breast lumps,because of their low costs and fairly accurate results,When difficulties are met with ultrasonography,99mTC-tetrofosmin may give some help.
