Although high B0 is not necessarily optimum for hyperpolarised lung imaging, it is of technical interest to evaluate the methods at higher B0. In this work a 2D SSFP sequence was evaluated for HP 3He lung MRI at the higher B0 of 3T. The results obtained with 2D SSFP in HP 3He phantoms and human lungs are compared with 2D SPGR and the effects of B0 and B1 inhomogoneity at the higher B0 are discussed.
