3D Radial mDIXON Acquisition for Improved Breast Imaging

Motivation: Breast magnetic resonance imaging (MRI) is a sensitive technique for staging and screening for breast cancer, however, it is susceptible to motion artifacts and inhomogeneous fat saturation. Goal(s): Demonstrate that 3D radial mDIXON acquisition provides robust motion suppression and homogenous fat saturation. Approach: Compared image quality of 3D radial mDIXON to 3D Cartesian mDIXON and 3D Cartesian with spectral fat saturation. Advanced postprocessing was also performed on the 3D radial mDIXON to see if additional diagnostic information could be obtained. Results: 3D radial mDIXON of the breast showed constantly high image quality with less motion artifacts and homogenous fat suppression. Impact: 3D radial mDIXON provides many advantages over Cartesian spectrally fat saturated acquisitions. The radial acquisition is less sensitive to motion artifacts. mDIXON provides consistent fat suppression compared to spectral fat suppression. Advanced postprocessing of mDIXON images provides further diagnostic utility.
