Dynamic MRI of Grid-Tagged Hyperpolarized Helium-3 for the Assessment of Lung Motion during Breathing

PURPOSE: To develop a dynamic magnetic resonance imaging (MRI) tagging technique using hyperpolarized helium-3 (HP He-3) to track lung motion. METHODS AND MATERIALS: An accelerated non-Cartesian k-space trajectory was used to gain acquisition speed, at the cost of introducing image artifacts, provid...
