Pairs of gradient echo (GRE) and balanced steady-state free precession (bSSFP) images with iron(II,III)oxide (IO) marker artifacts for different combinations of technical parameters and IO concentrations. Baseline image: sagittal scan of phantom with inserted guidewire enhanced with 6.25 mg/mL IO markers (phase encoding direction [PED] perpendicular, slice thickness [ST] 5 mm). The other image pairs deviate from the baseline images with different PED, ST, echo time (TE), or IO concentrations. TR Repetition time
