摘要： Apparatus, methods, and other embodiments associated with multi-slice blipped TrueFISP-CAIPIRINHA in magnetic resonance imaging (MRI) are described. One example apparatus produces CAIPIRINHA phase cycling in a TrueFISP-CAIPRINHA pulse sequence using a blipped gradient pattern rather than using radio frequency (RF) pulses. The phase cycling is produced by controlling a gradient coil in an MRI apparatus to produce a pre-scan pulse that is configured to set magnetization into a steady state position and then controlling the gradient coil to produce a balanced alternating phase pulse per repetition (TR). The balanced alternating phase pulse is configured to introduce a CAIPIRINHA aliasing pattern between slices. Controlling the gradient coil includes selectively adding and removing a finite gradient area from de-phase pulses and re-phase pulses in the pulse sequence.
