## Abstract Diffusion MRI of hyperpolarized ^3^He shows that the apparent diffusion coefficient (ADC) of ^3^He gas is highly restricted in the normal lung and becomes nearly unrestricted in severe emphysema. The nature of this restricted diffusion provides information about lung structure; however,

## Abstract In this study, MRI of hyperpolarized ^3^He gas in human para‐nasal sinuses is presented. Helium images were obtained at 1.5 T, using a surface coil and a 2D, fast gradient‐echo sequence with a nominal constant flip angle of 12°. Coronal images of 20‐mm thick slices were generated and co
