Shouldn't: If u/s clear, should be good to go. If they still want a cta, is fair to ask & get rationale, as aren't free--$/dye/rad--it's a reasonable question. If do have to get it, not a huge radiation load as mostly soft tissues.

Dr Lebowitz and another doctor agreed

No : If us is normal you probably do not need cta.
