We present an application of Variable-Blipped-EPI (VB-EPI) with readout-segmented EPI1, which has possible benefits for functional Magnetic Resonance Imaging (fMRI) experiments. Acoustic noise is reduced by lowering the amplitude of the readout (RO) gradient, which is possible due to the RO segmentation, and by prolonging the duration of the phase encoding (PE) blips simultaneously. Even with standard Cartesian parallel imaging techniques, like Generalized Autocalibrating Partially Parallel Acquisitions (GRAPPA)2, high resolution images can be obtained with high image quality.
