Breast MRI is a valuable diagnostic tool for certain patients. It typically is used in addition to, not in place of, a mammogram. This adds a second screening tool after inconclusive mammograms. Breast MRIs are also used when mammograms indicate a potential problem.
In such cases, Breast MRI can help determine whether lesions are cancerous. The procedure may even spare the need for a biopsy. However, even if a biopsy is necessary, an MRI-guided biopsy can aid in accurate diagnosis.
