The Linear Response Equilibrium Sequence (LRE) can be used as a time and energy efficient MR sequence for 1H-spectroscopy. In this study, we tailor the LRE sequence for cholesterol ester detection. Sequence intrinsic aliasing of sidebands can be suppressed by a change in the pulse pattern exciting a dual steady-state. In addition, a frequency selective water suppression module has been introduced into the LRE sequence. Measurements performed on a phantom filled with liquid cholesterol linoleate proved the performance of the new sequence elements.
