Can a Cohen Visit the Bodies Exhibit or is Tumah: Ritual Impurity a concern?

The exhibit displays desecrated human bodies, and it would be assur to go be entertained by it. If a Cohen is a medical student, then for pikuach nefesh he (along with any other medical student) would be allowed to go, but only for the purpose of studying the bodies, not just to see "art" or be "entertained".
