MATLAB: How to locate dicom images

dicomfoldername

So now I have:
[filename, pathname] = uigetfile();
set(handles.edit5, 'String', pathname);
img = zeros(165,127,168,'uint8');
for ii = 1:168;
    img(:,:,ii) = dicomread([pathname '\' num2str(ii,'%04i') '.dcm']);
end;
And it only works if there are exactly 168 images (165×127 pixels) in the folder and if they are numbered as: 0001, 0002, 0003, and so on. And it stores it as a 3D matrix name img.
How can I make code that it works with any number of dicom images of any size and any name and that it stores them as now, in 3D matrix called img.
Thanks.

[filename, pathname] = uigetfile();
if ~ischar(filename)
  return;
end
set(handles.edit5, 'String', pathname);
fileList = dir(fullfile(pathname, '*.dcm'));
fileList = fileList(not([fileList.isdir]));
nFile = numel(fileList);
imgC = cell(1, nFile);
for ii = 1:nFile;
  imgC{ii} = dicomread(fullfile(pathname, fileList(ii).name));
end
Of course you can store pictures in a 3D-array only, if they all have the same size. If this is true:
imgSize = size(imgC{1});
if all(cellfun('size', imgC, 1) == imgSize(1)) && ...
   all(cellfun('size', imgC, 2) == imgSize(2))
  img = cat(3, imgC{:});
else
  error('Pictures have different sizes.');
end
