1. A method for controlling a magnetic resonance imaging (MRI) apparatus, comprising: controlling a magnetic resonance imaging (MRI) apparatus to excite an object to be imaged using a multi-echo pulse sequence; controlling the MRI apparatus to acquire a data set from the object to be imaged as a function of performing a non-Cartesian, under-sampling acquisition, where the data set includes data acquired at two or more echo times (TE) per repetition (TR), and where an element in the data set is sampled two or more times; and controlling the MRI apparatus to reconstruct an image of the object to be imaged from the data set, where controlling the MRI apparatus to reconstruct the image of the object to be imaged from the data set comprises: selecting elements of the data set from which the image is to be reconstructed as a function of a pixel property, where a member of the data set acquired at a first TE has a first pixel property value and where a corresponding member of the data set acquired at a second TE has a second pixel property, or combining two or more corresponding elements of the data set from which the image is to be reconstructed where a first corresponding element is acquired at a first TE and where a second corresponding element is acquired at a second TE.
