Application of Fat Suppression Effect in MRI

Abstract

Magnetic resonance imaging is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. Separation of the two components into water-only and fat-only images can improve diagnosis, and is the premier non-invasive method for measuring the amount and distribution of fatty tissue. Fat-water imaging (FWI) enables fast fat/water separation by model-based estimation from chemical shift encoded data, such as multi-echo acquisitions. Qualitative FWI is sufficient for visual separation of the components, while quantitative FWI also offers reliable estimates of the fat percentage in each pixel. The major problems of current FWI methods are long acquisition times, long reconstruction times, and reconstruction errors that degrade image quality(Berglund 2011). The relationship between phantom structure and composition of density can observe on the three deferent composition of (oil, water. Oil &water), the MRI has many advanced techniques needed to be applied and used in Sudan to advance diagnosis and therapy, the methodology adopted were experiment the three phantoms under spin technique and advance technique and monitor the analyzed image, we found that the advanced technique has more accurate results than the spin, the conclusion of this research that the diagnosis can be more precise by using the MRI advance technique.
