Advanced Breast MRI Techniques: Helpful for Screening Breast Cancer?

Breast magnetic resonance imaging (MRI) is increasingly used in conjunction with mammography as a screening tool to detect breast cancers in asymptomatic high-risk women. Conventional dynamic contrast-enhanced (DCE) breast MRI has a high sensitivity but only moderate specificity for the detection of breast cancer. The primary goal of developing and applying advanced breast MRI techniques that can assess tissue biology is to improve lesion specificity. This review provides a summary of the advances in DCE-MRI techniques and the use of diffusion-weighted imaging and magnetic resonance spectroscopy for breast cancer detection. Publications on the use of these advanced MRI techniques are largely single-institution studies with small numbers of patients, which limits the generalization of this data to a wider screening population. In their current forms, these adjunctive techniques require further research, incorporating an expanded patient population, to validate their utility for breast cancer screening.
