Freehand Masking a DICOM image?

Is it possible to freehand mask a DICOM image? I have located a demo from another thread from Image Analyst, however it uses a Matlab demo image. I was wondering if it were possible to locate and use a DICOM image in this demo code for freehand masking? Thanks.

Nevermind! Have sorted it out! Thanks.

Yes it is possible to use imfreehand on any image.

Sorry I should have been more specific.

I'm using a demo with the following code.

% Read in a standard MATLAB gray scale demo image.
folder = fileparts(which('cameraman.tif')); % Determine where demo folder is.
baseFileName = 'cameraman.tif';
% Get the full filename, with path prepended.
fullFileName = fullfile(folder, baseFileName);
% Check if file exists.
if ~exist(fullFileName, 'file')
	% File doesn't exist -- didn't find it there.  Check the search path for it.
	fullFileName = baseFileName; % No path this time.
	if ~exist(fullFileName, 'file')
		% Still didn't find it.  Alert user.
		errorMessage = sprintf('Error: %s does not exist in the search path folders.', fullFileName);
		uiwait(warndlg(errorMessage));
		return;
	end
end
grayImage = imread(fullFileName);
imshow(grayImage, []);
axis on;
title('Original Grayscale Image', 'FontSize', fontSize);
set(gcf, 'Position', get(0,'Screensize
')); % Maximize figure.

However, I want the image to be one of my own which is a DICOM image. However, it says the file extension is not recognised when I use it. Is there anyway I can swap in my own DICOM image? Thanks
