We recently proposed a novel method for reduced FOV excitation using spatial-spectral RF pulses and second-order gradients. The method leverages the unique spatial dependence of the second-order gradients to excite a circular region-of-interest in a thin slice using a 2D spatial-spectral RF pulse. This work presents the first experimental results of the method on a 3.0T commercial MRI scanner.
