True, true, pictures are even one level higher in terms of difficulty to anonymise right (and that's not even what they are asking, here it's about structured text records). FYI, high-res face MRI are just pictures of the face. So yes, if you share the picture of the face of someone, they may find your identity back, but it's not specific to MRI. Dealing with any medical record that contains pictures of patient you should take additional steps to prevent identification, and face is the most sensitive part of the body as it can be most likely identified. If tomorrow there are publicly available anonymised close-up pictures of cardiac MRI, it'd be extremely challenging to map them to their real owner with a 100% certainty but the discoveries it could lead to are very exciting (and the same with skin cancer pictures for example, or suspiciouses moles)
