With recent
developments in ultra-short TE (UTE) MRI sequences such as PETRA with the respiratory
triggering and the segmented acquisition, MRI has shown a potential of being a
viable radiation-free alternative to the incumbent gold standard CT lung
imaging. Within a volunteer validation
study (n=14), the current work demonstrates a recent progress in the PETRA lung
MRI towards its robustness and its applicability to all patient populations. The
proposed solution improves patient comfort and image contrast by suppressing
the unintended high intensity signals from surrounding tissues.
