F MRI of the lungs is a new pulmonary
imaging modality that uses inhaled inert fluorinated
gases as a signal source to acquire images of the lungs.
The purpose of this study was to investigate optimized
image acquisition strategies by optimizing and comparing
UTE and gradient echo images in both a resolution
phantom and healthy volunteers. Overall, UTE lung images
had a higher SNR than gradient echo images, but also had
poorer edge definition. On the other hand, gradient echo
images had a lower SNR than UTE, but showed more edge
detail and had a higher resolving power.
