A novel interleaved sequence is presented in this work that allows acquisition of 3He ventilation, ADC, T2* and B1 maps simultaneously in-vivo. B1 maps were used to corrected the ventilation image for the artifacts due to the B1 inhomogeneities, while Compressed Sensing scheme was used to accelerate the temporal resolution. The sequence was tested in three healthy volunteers and the values of parameters obtained are in accordance with previously published results.
