[Differentiation of benign and malignant palpable breast masses using 99mTc-MIBI imaging]

Forty-two patients with palpable breast masses were examined by 99mTc-MIBI imaging. All the results were compared with ultra-red scanning and B-ultrasongraphy. By pathological examination 26 out of 42 cases had breast carcinoma, 16 patients benign lesions. The sensitivity of 99mTc-MIBI imaging was 92.3%, the specificity was 96.0% and the accuracy 92.8%, which were higher than those of ultra-red scanning and B-ultrasound (P < 0.01). The authors consider that 99mTc-MIBI breast imaging is useful in distinguishing malignancies from benign breast masses.
