Robust High Resolution Fat-Water Separation in the Abdomen During Free-Breathing by Self-Gated 2D Radial TrueFISP Imaging

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 a self-gated reconstruction 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.
