Description: A major limitation to achieving fast imaging with breast MRI is the necessity of a fat suppression process, since the lipid signal appears bright in MRI and may otherwise be misidentified as a lesion. The goal of this document is to thoroughly discuss current methods of fat suppression, and to investigate a means to reduce scan time while still achieving effective reduction in fat signal. A method is proposed by which a specific fat suppression technique, fat saturation, is applied less frequently to save time. Within the capacity of this method, the variable parameters are investigated and optimized in an attempt to produce images with the least fat contamination in the shortest period of time. This technique is demonstrated in phantoms and in-vivo, and compared with other fat suppression techniques upon which it has advanced.
