VSOP COGNAC is a acquisition strategy, that reduces the FOV by combining phase encoding with a z2-gradient and sinusoidal gradient pulses on the Cartesian gradients. This acquisition scheme intrinsically dephases the spin ensemble at the center of the FOV, thus a reduction of the phase encoding steps can be achieved without violating the Nyquist criterion. This potentially allows faster imaging e.g. of the cortex, when the center of the FOV is of no interest.
