Pseudo Steady‐State Free Precession for MR‐Fingerprinting

This article discusses the signal behavior in the case the flip angle in steady‐state free precession sequences is continuously varied as suggested for MR‐fingerprinting sequences. Flip angle variations prevent the establishment of a steady state and introduce instabilities regarding to magnetic field inhomogeneities and intravoxel dephasing. We show how a pseudo steady state can be achieved, which restores the spin echo nature of steady‐state free precession.
