Filters are given by pulse sequences which, in most cases, generate longitudinal magnetization which differs from the thermodynamic equilibrium state in some specific way [99, 100]. Many different filters can be conceived and combined to produce parameter weights of spin density images. Basically, any pulse sequence can be considered a magnetization filter, but particularly useful ones are...
