Note: there are sometimes PET series with a tiny gap between several slices. The origin of this problem is unknown, probably some hardware or setup issue. Such series will be marked as non-uniform. It is possible to increase maximum tolerance for equidistant slices. Set e.g. to 0.02 and try to reload series. See Settings, DICOM, Advanced.
