Torecognize different lesions that can be found outside the breastwhen performing abreast Magnetic Resonance Imaging (MRI), and to be familiar with their appearance in various pulse sequences. To understand the potential information that can be extracted from breast MRI in addition to the branch concerned with breast disease.

Breast MRI has become an important tool in breast imaging with multiple diagnostic indications. It plays a key role in decision making of breast cancer treatment. For these and other reasons it is a diagnostic test performed with increasing frequency in a growing number of Centers all around the world.
