2010 Journal of Magnetic Resonance Imaging  
Purpose: To propose and test the feasibility of a novel method for quantifying 3D regional pulmonary kinematics from hyperpolarized helium-3 tagged MRI in human subjects using a tailored image processing  ...  Materials and Methods: Following image acquisition, inspiratory and expiratory tagged 3 He magnetic resonance (MR) images were preprocessed using various image filtering techniques to enhance the tag surfaces  ...  Recent developments in lung MRI using hyperpolarized helium-3 and MR tagging techniques have paved novel investigatory avenues for quantifying pulmonary kinematics (3) (4) (5) (6) .  ...
