[The feasibility of magnetic resonance tomography in the diagnosis of non-palpable breast tumors].

This study deals with the role of MRI in elucidating clinically silent lesions of the breast with indeterminate changes on mammography. MRI localisation of suspected lesions was possible in all cases by using double coils after contrast enhancement of the glandular tissue, independent of the findings on mammography. Inability to demonstrate micro-calcification did not prove a disadvantage. MRI cannot provide a definite tissue diagnosis, since there is overlap between the appearances of malignant and benign lesions.
