In this study, the upper-limit volume (gas plus partial tissue volume) as well as absolute volume (gas only) of lungs measured with hyperpolarized (3)He-MR imaging is compared with that determined by micro-computed tomography (CT) under similar ventilation conditions in normal rats. Five Brown Norwa

## Abstract Images of hyperpolarized ^3^He were acquired during breath‐hold in four healthy volunteers with the use of an optimized 3D gradient‐echo sequence. The images were compared with existing 2D gradient‐echo methods. The average SNR from a 13‐mm‐thick slice in the peripheral lung was 1.4 tim

## Abstract A novel imaging method is presented, Flip Angle Variation for Offset of RF and Relaxation (FAVOR), for rapid and efficient measurement of rat lung ventilation using hyperpolarized helium‐3 (^3^He) gas. The FAVOR technique utilizes variable flip angles to remove the cumulative effect of
