I may be a nerd, but I think this is easily the coolest picture I have seen since I've started my rotations.  This is a 3D reconstruction of one of my patient's abdominal aortic aneurysm and abdominal blood vessels from a CT scan.  The fact that we can see to this detail something going on inside of a patient without having to open them up at all is incredible to me.  The ballooning out where the arrow is pointing shouldn't be there and is dilated because of a weakening of his vessel.  These aneurysms are at risk for rupturing and can be very serious and life threatening.  The faint red shapes above and beside the aneurysm are where his kidneys are, which you can see in the cartoon representation as well.
