Abstract

Systems and methods for acquiring magnetic resonance imaging (MRI) images of a subject are provided. The method includes performing a pulse sequence to elicit spin echoes, wherein the pulse sequence includes a radio frequency (RF) excitation pulse and a series of RF refocusing pulses that refocus echoes with flip angles in the series of RF refocusing pulses that are varied. The method also includes scaling MRI data associated with each echo by a correction factor that is determined for each echo to create scaled MRI data and that is not the same for all echoes. The method then includes reconstructing an image of the subject using the scaled MRI data.
