Quantification of Breast Stiffness Using Magnetic Resonance Elastography at 3T with a Soft Sternal Driver: A Reproducibility Study

摘要

PurposePrevious studies of breast MR elastography (MRE) evaluated the technique at magnetic field strengths of 1.5T with breast in contact with the driver. The aim of this study is to evaluate breast stiffness measurements and their reproducibility using a soft sternal driver at 3T and compare the results to qualitative measures of breast density.
