An 19F-1H linear dual tuned RF birdcage coil was
designed for inert fluorinated gas MRI in the lungs of
rats. In order to test the homogeneity of the coil, B1
field mapping was performed in phantoms using mineral
oil for the 1H channel (0) and sulfur hexafluoride
(SF6) for the 19F channel (90). A rat was ventilated
using a custom-built ventilator with a mixture of 80%
SF6 and 20% O2. 1H MR images were initially acquired for
localization and then 19F free breathing lung images
were acquired using a 3D gradient echo.
