I think this falls under the auspices of "just because you can,  
doesn't mean you should!".  (i feel) Airing out the personal medical  
information of an individual is not professional nor ethical, and it  
really isnt our personal decision to decide the terms of what we feel  
will cause no harm if we share it.
Maybe mrs "smith" doesn't feel it's anyones business she had a CT scan  
no matter how good she looks. That's how rumors start that can take on  
a very painful life of their own. It's cavalier sharing of personal  
medical information that created the HIPPA governing in the first place
