WebThe formation of a GRE is illustrated schematically. Following the RF pulse, the first negative-going lobe of the gradient causes a phase dispersion of the precessing spins. … WebGradient spoiling The easiest spoiling method to understand is gradient spoiling, in which a gradient pulse is used to create a range of phase angles across a voxel. This ‘dephasing’ effect causes the transverse …
