CTs are uncommon in family medicine offices. They'd need to forfeit square feet that could otherwise be used for several exam rooms. The offices that do have them probably opt for really low-end ones. So "never"?

As an aside, I think GPs (General Practitioners) are probably phasing out a bit in favor of Physician Assistants and Nurse Practitioners. Though "Family Medicine" still employs lots of MDs.
