The first ISMRM sponsored Workshop on Fat-Water Separation, co-organized by Diego Hernando and Scott Reeder in 2012, brought together experts in imaging and medicine to discuss developments in imaging body and organ fat deposition. This workshop included historical and clinical perspectives, as well as updates on advanced quantitative biomarkers and development of applications throughout the body. As part of this workshop, the organizers, led by Diego Hernando and Harry Hu, compiled a Fat-Water Toolbox that included multiple recent (at the time) algorithms and datasets for fat-water separation (ISMRM login required). Over the past few years, this toolbox has facilitated the dissemination of algorithms for applied MRI research, and the development of new algorithms, eg. as part of the 2012 ISMRM Reconstruction Challenge.
Sometimes I get questions about how to choose echo times for fat-water separation or PDFF/R2* quantification. Here is a Jupyter Notebook with some interactive simulations and calculations:
