Lung imaging in small animals is particular difficult
due to small anatomy dimensions, high respiratory and heart rate and the very
short T2* value in high magnetic fields. With 2D tyGA UTE it is feasible to generate lung
images in small rodents with sufficient quality to quantify PF and FV at 11.7T.

and axial slice orientation. The grey lines indicate the position of the slice
in the respective other orientation.
