Abstract
A method of magnetic resonance imaging includes supporting a subject in an examination region of an MRI scanner(A). An MRI pulse sequence is applied to produce a detectable magnetic resonance signal (100) in a selected region of the subject. The magnetic resonance signal (100) includes a plurality of echos (102a-h) which are received. The plurality of received echos (102a-h) are subjected to a controllable gain factor such that at least two echos are subjected to different gain factors. In this manner, for example, a multi-contrast acquisition and imaging experiment may be achieved with each set of acquired echos and/or each image having a separately optimized (e.g., optimized for SNR considerations) gain factor individually selected and/or set therefor.
