Purpose
To evaluate T2,
, and signal‐to‐noise ratio (SNR) for hyperpolarized helium‐3 (3He) MRI of the human lung at three magnetic field strengths ranging from 0.43T to 1.5T.
Methods
Sixteen healthy volunteers were imaged using a commercial whole body scanner at 0.43T, 0.79T, and 1.5T. Whole‐lung T2 values were calculated from a Carr‐Purcell‐Meiboom‐Gill spin‐echo‐train acquisition.
