Description
Magnetic Resonance Fingerprinting (MRF) promises quantitative tissue analysis based on the relaxation times. Spiral undersampling is employed with MRF to yield short scan times. However, it is prone to blurring artifacts in the presence of field inhomogeneities, especially if both aqueous and fatty tissues are present. In this contribution, we extend MRF to quantify the fat signal fraction and simultaneously correct for spiral blurring. Thereby, improved spatial information about the tissue relaxation times as well as the fat signal fraction is retrieved. We present the application to female breast imaging.
