Dixon technique
I have been searching the web for information regarding a "double-echo two-excitation pulse sequence encoding fat and water signals for a phase-sensitive three-point Dixon type analysis". Does anyone know what pulse sequence(s) this is referring to, or a publication that might be helpful???
Thanks

Hi, You may start with checking the MRI candidate sites whether their MRI is equipped with following package: IDEAL IQ for GE MRI scanner, mDIXON-Quant for Philips MRI scanner, LiverLab for Siemens MRI scanner. This shall shall exclude some candidates and save a lot efforts. Certainly there will be other concerns if it's a multi-center study. This article may help: https://www.birpublications.org/doi/pdf/10.1259/bjr.20170378

Muscle shading in 3T Images
Try running a B1 Map followed by Calibration. Set RF Drive mode to Optimized. This is supposed to optimize for your Patient. Supposed to reduce dielectric effect/shading for Lumbar and Abdomen.
You can find under GE Additional Abdomen Sequences.

Or you can run Ideal with Dixon technique. Turn on IN phase will give you T1 FS & IN Phase is you plane T1. I believe this takes care of the artifact.

Dixon technique
Dixon technique uses alternative water/fat phase-encoding strategies. The technique is generalized to phase encoding of theta radians, and the signal-to-noise ratio (S/N) performance is evaluated.To get some more information regarding this please check out the following link : http://www.ncbi.nlm.nih.gov/pubmed/18777528
