How can I get pixel spacing value from DICOM images?

An old code (written in 2010) of DICOM image viewer is in my hand and it achieves the image's pixel spacing value by the following code snippet (A bit edited from the original):

d = sortDirectory(folder); %Sort in ascending order of instance number
metadata = dicominfo(d(1).name);
[group1 element1] = dicomlookup('PixelSpacing');
resolution = metadata.(dicomlookup(group1, element1));

Turns out, DICOM metadata no longer carries the PixelSpacing attribute. So I cannot get it by calling "dicominfo" function. How can I get this info now?

Thanks in advance.

let say your image is "image.dcm"

info=dicominfo('image.dcm');
spacing=info.PixelSpacing;
spacing=
