[Diagnosis of breast tumors by scintigraphy versus mammography].
OBJECTIVE
To compare the efficacy of the breast scintigraphy with 99mTc-MIBI in the detection of breast lesions versus mammography.


METHODS
Cross sectional study.


METHODS
A concentration oncologic hospital in Mexico City.


METHODS
56 women with a biopsy performed due to radiologic suspicion of mammary cancer were included as well as 10 normal women. MAIN PROCEDURES: Mammography, breast scintigraphy with 99mTc-MIBI, and biopsy were performed.


RESULTS
Sensitivity of breast scintigraphy was 100% specificity 94.6%, PPV 90% and NPV 100%; sensitivity of the mammography was 100%, specificity 54% PPV 52.7%, and NPV 100%.


CONCLUSIONS
Breast scintigraphy with 99mTc-MIBI showed a higher sensitivity and specificity than those of mammography. It was highly reliable for the diagnosis of mammary gland malignant lesions.
