Mel,

I can't quite remember Alan's symptoms right now - I am thinking he has more than pain and burning in three toes, not that that isn't enough!

As others are saying, Morton's can be diagnosed clinically (without other tests, such as imaging) by a skilled practitioner. X-rays are not used to make that diagnosis - but they can turn up other things that would explain such a problem and thus can be used to rule out Morton's.

Ultrasound is usually preferred today. But you should make sure that an experienced operator does the test, using high-resolution. Doing this procedure does require some specialized training, practice, and an appropriate skill set. If there is any doubt about the conditions of the test, then it could be better to have an MRI.

I have found that sometimes the docs go the other way in terms of familial stuff. In my case, for instance, when the family connection was uncovered, there was a tendency to just go with it. I was afraid that the other possibilities that were still on the board might get dropped off.

I am guessing that there may be all kinds of reasons why familial conditions either get pooh-poohed, or jumped on as THE answer.

As usual, your detective work is paying off yet again. It is amazing what we find that we can do when it is important enough. All of your natural and learned skills wouldn't mean much, if you didn't really care so deeply.
