AB - <jats:title>Abstract</jats:title><jats:p>Balanced steadystate free precession (SSFP) is hindered by the inherent offresonance sensitivity and unwanted bright fat signal. Multipleacquisition SSFP combination methods, where multiple datasets with different fixed RF phase increments are acquired, have been used for shaping the SSFP spectrum to solve both problems. We present a new combination method (weightedcombination SSFP or WCSSFP) that preserves SSFP contrast and enables bandingreduction and fatwater separation. Methods addressing the banding artifact have focused on either getting robust bandingreduction (complexsum SSFP) or improved SNR efficiency (sumofsquares SSFP). The proposed method achieves both robust bandingreduction and an SNR efficiency close to that of the sumofsquares method. A drawback of fat suppression methods that create a broad stopband around the fat resonance is the wedge shape of the stopband leading to imperfect suppression. WCSSFP improves the suppression of the stopband without affecting the passband performance, and prevents fat signal from obscuring the tissues of interest in the presence of considerable resonant frequency variations. The method further facilitates the use of SSFP imaging by providing a control parameter to adjust the level of bandingreduction or fat suppression to applicationspecific needs.
