Understanding the Dixon Method for Fat-Water Separation in MRI

The Dixon method exploits the chemical shift between fat and water protons to separate their signals, producing four image sets (water-only, fat-only, in-phase, opposed-phase) from a single acquisition.

• Based on in-phase and out-of-phase echoes to decompose signal.
• Common variants include two-point, three-point, and multi-point Dixon.
• Educational Q&A from MRI Questions blog (Elster); not a research study.
