The use of respiratory Self Navigation for 3D Whole
Heart Phase Sensitive Inversion Recovery (PSIR) has not
been exploited yet, since such acquisitions are
characterized by strong contrast variations. An
Iterative approach to SN showed to successfully
compensate for respiratory motion and to enable 100%
scan efficiency for PSIR applied to late Gadolinium
enhanced imaging of the heart.
