Breast MRI technique

Abstract

Although there is no single standard protocol for breast MRI acquisition, high quality breast MRI generally requires use of a dedicated breast MRI coil and adequate (≥ 1.5 T) magnetic field strength. Currently, breast MRI requires gadolinium contrast agent administration for cancer detection and a dynamic acquisition (dynamic contrast enhanced, or DCE, MRI) using a method that allows for homogenous fat suppression. In order to maximize sensitivity and sensitivity, MRI protocols must balance spatial and temporal resolution so that important morphologic and kinetic enhancement features can be readily identified. In addition, it is important to develop an approach that attains consistency, addresses technical challenges, and minimizes artifacts. Finally, advanced approaches, such as use of higher magnetic field strength (e.g. 3 T) scanners, diffusion weighted imaging, and MR spectroscopy present unique opportunities and challenges that must be considered and addressed prior to adoption in routine clinical practice.
