Hyperpolarized (3)He MRI of the human lung was performed at 0.54 and 1.5 T using identical software and hardware (except for RF coils) at both field strengths. The T(*) (2) of (3)He gas in the lung was measured, and the effects of magnetic-susceptibility-induced field inhomogeneities on the appearance of interleaved-spiral and interleaved-echo-planar lung images at 1.5 T were compared to those at 0.54 T. Mean T(*) (2) values for (3)He gas in the healthy human lung were 26.8 +/- 1.5 ms and 67.9 +/- 1.3 ms at 1.5 and 0.54 T, respectively. At 0.54 T, interleaved-spiral images showed markedly less blurring due to susceptibility effects compared to images acquired at 1.5 T. At both 0.54 and 1.5 T, interleaved-echo-planar images appeared essentially identical to corresponding GRE images, even though the data-sampling period per echo and echo time were substantially longer for the interleaved-echo-planar images acquired at 0.54 T.
