 In addition to the gold standard imaging of mammography and breast ultrasound, magnetic resonance imaging MRI has become a well established investigational modality for the diagnosis and staging of breast cancer. MRI demonstrates increased sensitivity and specificity relative to both mammography and breast ultrasound in the screening of women with an increased risk of breast cancer development i.e. familial history of disease and or genetic predisposition and those who have very dense breast tissue. MRI has also proved to be very sensitive in the detection of multi-focal, multi-centric breast lesions, permitting the accurate staging of disease. However, despite this demonstrated efficacy, the standardization of MRI studies from one Institution to another is often difficult as each Institution will have a standard breast protocol with sequences set in accordance to the manufacturer of the machine and the manner in which the breast examinations have been designed.
