    Parameters
    ----------
    image: img-like object or str
        Can either be:
        - a file path to a .mhd file. (if it is a .raw file, this won't work).
        - any object with get_data() and get_affine() methods, e.g., nibabel.Nifti1Image.
        If niimg is a string, consider it as a path to .mhd image and
        call load_raw_data_with_mhd on it. If it is an object, check if get_data()
        and get_affine() methods are present, raise TypeError otherwise.

    make_it_3d: boolean, optional
        If True, check if the image is a 3D image and raise an error if not.

    Returns
    -------
    result: nifti-like
       result can be nibabel.Nifti1Image or the input, as-is. It is guaranteed
       that the returned object has get_data() and get_affine() methods.
