How to display an image using the referencing obtained with imref3D?

Hello,

I'm trying to display some 3D DICOM images using the world reference frame. So I have read my volume and applied imref3D as follows for a case that contains 83 slices:

RI=imref3d(size(I),PixelSpacing(1),PixelSpacing(2),SliceThickness);
RI.ZWorldLimits=[inf{1}.ImagePositionPatient(3) inf{83}.ImagePositionPatient(3)];

The way I would usually display one of the slices is by

imagesc(I(:,:,10))

but this will display it in the intrinsic reference frame

I tried following the example in this link http://blogs.mathworks.com/steve/2013/08/28/introduction-to-spatial-referencing/

and tried using

figure, imshow(I(:,:,1),RI);

but I get the error "Spatial referencing inputs to imshow must be 2-D."

Can someone help me with this? Also, is it possible to render the volume? and can I use imagesc instead of imshow?

Any help is appreciate it. Thank you in advance.
