This lung_001.nii.gz image seems to be quite unusual, i.e., messed up.
Float scalar type does not make sense for clinical CTs, so change that to short. Do not choose Int, as that would be 32 bits per voxel, which would be unusual, too.
The IJK coordinate system is a left-handed coordinate system (determinant of the IJK to RAS direction matrix is negative, so the transformation turns the volume inside out). You can fix this by resampling the volume using Crop volume module with the default settings (you don’t need to crop away any part of the volume, you just take advantage of that Interpolated cropping enables resampling and the module always uses right-handed coordinate system for IJK).
Nifti is for brain imaging. For general imaging purposes, use nrrd instead. Nifti has many issues, for example it is very easy to mess up the image orientation (as it is stored in Nifti in a complex, redundant way and interpretation of non-trivial cases is inconsistent between different applications).
