MRI of breast tumors

Breast MRI is increasingly used as an adjunct to conventional imaging modal ities, particularly in diagnostic problem cases, but also for pre-operative staging. It is an extremely sensitive technique, with relatively limited s pecificity. To avoid both, false-positive, but particularly false-negative diagnoses, it is imperative to be familiar with the varying MRI appearance of benign and malignant breast tumors. This review serves to give an overvi ew of the different criteria that can be used for differential diagnostic p urposes. Moreover, practical guidelines are given to help with the adequate management of enhancing lesions.
