Imaging performed on symptomatic patients, or to work-up an abnormality found on screening mammography. The objective is to use imaging to typify pathology and arrive at a diagnosis. This is important because different diagnoses have significantly different outcomes and survival rates. For instance, a diagnosis of a simple breast cyst has few implications and does not affect the patient's life expectancy. In contrast, a diagnosis of breast cancer has significant implications for the patient and their life expectancy.
Dynamic contrast-enhanced (DCE)-MRI provides information about the morphology and function of a lesion with high sensitivity but moderate specificity (72%) which leads to subsequent patient work-up and biopsies with results that indicate benignity. As a consequence, other MRI sequences, in addition to DCE-MRI images have been introduced in the routine breast MRI exams. This approach has been defined as multiparametric MRI (mpMRI), in which T2-weighted (T2w) MRI is frequently used.
