Synopsis

Keywords: Lung, Data Analysis, ventilation, functional lung imaging, sencefulSElf-gated Non-Contrast-Enhanced FUnctional Lung imaging (SENCEFUL) is a well-established method to determine functional lung parameters and was already successfully combined with 3D-UTE for robust ventilation quantification. Nevertheless, the evaluation of not only ventilation, but also perfusion, requires a 2D excitation, as it is based on the inflow effect. Additionally, coverage of more than one slice within short measurement times is valuable. Here, it is shown that functional information can be obtained from two slices acquired simultaneously, thus doubling the anatomical coverage of a conventional 2D acquisition.
