Determination of optimal gadolinium concentration using SSFP for catheter-directed contrast-enhanced coronary MR angiography.

To determine the optimal gadolinium concentration for catheter-directed coronary magnetic resonance angiography (MRA) using magnetization-prepared steady-state free-precession (SSFP) in swine. ⋯ For catheter-directed contrast-enhanced coronary MRA, the ideal gadolinium concentration should maximize relative SNR and limit the total gadolinium dose. Using these criteria, of those concentrations we tested in the swine model, 8% injected gadolinium was superior for catheter-directed SSFP coronary MRA.
