Abdominal Fat-Water Separation in High Temporal and Spatial Resolution During Free Breathing

Riad Ababneh¹, Thomas Benkert², Martin Blaimer², Felix A. Breuer²

We present a robust approach to separate fat and water signals in the abdomen during free breathing. The approach combined with the k-space-weighted image contrast (KWIC) technique of different respiratory phases in free-breathing. In this study a radial TrueFISP sequence was modified, wherein TE was made to vary between subsequent readouts. Good separation without streaking artifacts or blurring due to respiratory motion was obtained in all studied cases.
