It is well-known that pulmonary ventilation exhibits a gravitational gradient due to a gradient in regional compliance. 19 F MRI, using inhaled inert fluorinated gases as a signal source, is expected to exhibit strong ventilation gradients, especially since the gas density is high. The purpose of this study was to perform 19 F 3D UTE imaging in healthy volunteers, and to measure anterior/posterior ventilation gradients. This preliminary study demonstrates a clear gravitational distribution gradient of inert fluorinated gases in human lungs, and there is a potential for this technique to provide functional and regional information regarding lung physiology.
