Abstract:
Purpose: To explore the clinical value of 99mTc-MIBI imaging in differentiating malignancies from benign breast masses. Methods: 195 patients underwent the examination for 99m Tc-MIBI. Comparative diagnosis was done by postoperative pathology in all cases. Results: 69 of the 84 cases of breast cancer were preoperatively diagnosed by 99mTc-MIBI, the causes of false-negative results were small size of the mass and the higher degree of malignancy. 102 of the 111 patients with benign lesions were scintimammographically negative, the cause of false-positive results was large fibroadenomas with surplus blood supply. The sensitivity was 82. 1%, specificity was 92.0%, and the diagnostic accuracy was 89.2%. Conclusions: 99mTc-MIBI examination is an effective, simple and noninvasive diagnostic method for primary breast cancer.
