Some types of breast cancer have a high incidence of contra-lateral occurrence. To provide the best service to the patient every breast evaluation for cancer should include not only the affected but also the contra-lateral breast. Since contrast agents (Gd) can only be administered once for the dynamic evaluation of contrast uptake, both breasts need to be scanned at the same time. The best orientation is transverse. High quality breast MR images have been acquired on various Siemens MR systems (1.0 T MAGNETOM Harmony, 1.5 T MAGNETOM Symphony and Sonata).
