I've always assumed that a CT scan is better at "hard" objects, while an MRI is better at "soft" objects, but then I heard that CT scans (even without contrast) can be used to diagnose soft body issues. So now I'm kind of confused:

  1. Are there things that an MRI (with contrast) can "see better" than a CT (with contrast)?

  2. Are there things that a CT (with contrast) can see better than an MRI (with contrast)?

  3. And, for that matter, are there places where an ultrasound can see better than an MRI or CT?

    General principles about this are readily available online, so would you mind to search on your own first and tell what have you've found?
