If you import through Slicer’s dicom module, you can enable the acquisition transform correction option (in the preferences) which automatically creates a nonlinear transform to put every slice in the location specified by the headers. You can then resample the volume through this transform if you need to have a regularly sampled volume like a 3D itk image.

Of course there’s not much that can be done if the data is corrupted, but the dicom patcher addresses some common cases.
