In this contribution, a rapid and robust technique for quantitative T 1 mapping of the human lung is presented. Based on a series of Snapshot FLASH tomograms acquired after a single inversion pulse, high quality and quantitative T 1 parameter maps acquired in under five seconds were obtained from six healthy volunteers. The measured T 1 values are in good agreement with previously reported literature values. T 1 maps were also acquired with the volunteers breathing room air or 100% O 2 . The T 1 difference between breathing room air and 100% O 2 is statistically significant at P < 0.0001. J. Magn. Reson. Imaging 2001;14:795–799. © 2001 Wiley‐Liss, Inc.
