Cardiac Gating

Cardiac Gating monitors the cardiac or respiratory cycle, but does not use a trigger to initiate RF application. RF is applied throughout the cycle at the defined TR, and data is acquired when the desired physiological event occurs.

Fast Card, FastCINE, 3D Fast GRE/SPGR, 3D Fast TOF (GRE/SPGR), FIESTA, and Fast 2D PC use Cardiac Gating.
