AB - <jats:title>Abstract</jats:title><jats:p>Balanced steadystate free precession (bSSFP) MRI is a rapid and signaltonoise ratioefficient imaging method, but suffers from characteristic bands of signal loss in regions of large field inhomogeneity. Several methods have been developed to reduce the severity of these banding artifacts, typically involving the acquisition of multiple bSSFP datasets (and the accompanying increase in scan time). Fat suppression with bSSFP is also challenging; most existing methods require an additional increase in scan time, and some are incompatible with bSSFP bandreduction techniques. This work was motivated by the need for both robust fat suppression and band reduction in the presence of field inhomogeneity when using bSSFP for flowindependent peripheral angiography. The large flip angles used in this application to improve vessel conspicuity and contrast lead to specific absorption rate considerations, longer repetition times, and increased severity of banding artifacts. In this work, a novel method that simultaneously suppresses fat and reduces bSSFP banding artifact with the acquisition of only two phasecycled bSSFP datasets is presented. A weighted sum of the two bSSFP acquisitions is taken on a voxelbyvoxel basis, effectively synthesizing an offresonance profile at each voxel that puts fat in the stop band while keeping water in the pass band. The technique exploits the nearsinusoidal shape of the bSSFP offresonance spectrum for many tissues at large (>50°) flip angles. Magn Reson Med, 2011. © 2011 Wiley Periodicals, Inc.</jats:p>
