Reading multiple image Tiff file

When I try to read a tiff image with imread I receive the warming:
" Only the first slice will be read from this image with depth 418 "
Which I understand. According to the documentation of imread, I schould then be able to acces the other slices by typig for example:
Image = imread(filename, 2).
However when I do that I get the message:
" Invalid TIFF image index 2 "
How can I read my entire tiff image (CT_Scan with 418 slices)?
imfinfo on this file returns the following information:

Hi Ingrid,
I'm having this same issue. What do you mean when you say you used the function Tiff? Are you using that instead of imfinfo? When I try:
tiffile = (Tiff(filename,2));
I get out:
Expected MODE to be one of these types:
char, string
Instead its type was double.
How did you end up making the multi-element struct for each TIF slice? Thanks!

@Noshin Nawar I think you're getting TIFF confused with read
The second argument to Tiff should be a letter. You probably want 'r' instead of 2.
Input Arguments
filename — Name of file
character vector | string scalar
mode — File access type
'r' (default) | 'w' | 'w8' | 'a' | 'r+'

Looks like it's not a multi-page TIFF, but a single page tiff with a 3-D volumetric image in it that has 418 slices. You can get the second slice (what you thought was a page) by indexing:
slice2 = image3D(:, :, 2);
