Review and audit of the post-surgical MRI breast: Pictorial essay.

Audit of contrast-enhanced breast MRI performed over a 3-year period in a single institution to describe and summarise the changes seen after surgery and radiation therapy for primary breast cancer, breast augmentation and oncoplastic surgery. Seventy women were identified and reviewed (100 breast MRIs in total). The most common change seen was haemosiderin deposition. The early changes of skin thickening, oedema, seroma and background parenchymal enhancement decreased with time leaving residual breast shrinkage, haemosiderin/calcification and architectural distortion due to fibrosis and scarring.
