Projecting everything might not look good, you can try a maximum intensity projection if the data is contrast enhanced, such as angiograms,
load('mri');
notAtAllAngio=squeeze(D);
imshow(squeeze(max(notAtAllAngio,[],3)),[]);
or you can try other fancy rendering methods, such as View3D, http://www.mathworks.com/matlabcentral/fileexchange/21993-viewer3d.

If you don't have x,y,z data, then use it's index, 1:512 for x and y, 1:23 for z, try
slice(data,100,200,10)
