[Value of magnetic resonance imaging in diagnosing breast lesions which need biopsy].
OBJECTIVE
To evaluate MRI in diagnosing breast lesions which need biopsy.


METHODS
One hundred and eight patients were admitted to hospital for biopsies due to one hundred and sixteen suspicious lesions detected in their breasts. These lesions were detected by physical examination, mammography or ultrasonography. They were also administrated MRI examination before biopsy. The sensitivity and specificity of each diagnostic method were obtained and the radiologic-pathologic correlation was meanwhile calculated.


RESULTS
Seventy (60.3%) breast lesions were diagnosed malignancy. The sensitivity, specificity, accuracy, positive prognostic value and negative prognostic value of ultrasonography were 83.3%, 62.0%, 74.1%, 74.3% and 73.8%. Such data of mammography were 86.8%, 68.1%, 78.0%, 75.4% and 82.1%. And those of MRI were 97.1%, 73.9%, 87.9%, 85.0% and 94.4%.


CONCLUSIONS
MRI is superior to ultrasonography and mammography in diagnosing breast lesions, especially for the nonpalpable lesions.
