Imaging of the beating heart is one of the main challenges in fast MRI. Balanced steady state free precession sequences are fast, yield high signal and have excellent contrast between blood and myocardium. Unfortunately, they are sensitive to field inhomogeneities, which lead to banding artifacts, considerably reducing the image quality. As the steady state tolerates small shifts in frequency it is possible to acquire a frequency- modulated bSSFP. Our study uses such a frequency-modulated approach in combination with a multi-frequency reconstruction to obtain banding free CINE images, with high signal and good contrast.
