From his comments defending not visiting ER given a recent unrelated health issue: The hospital billed $11,000 for a cat scan; the insurance paid 6k.'
Seriously, if you need a an elective scan and it's going to cost you more than a couple of grand after insurance: take a vacation, fly first class, stay in a 5 star hotel, get seen privately in a first class facility, have a relaxing rejuvenating break, and come home with change. Cost of a full-body CT scan in Europe?: < $1000.[1]
Cost of full body CT scan may be greater than that - it would likely put you in Hiroshima-survivor radiation dose range.
Edit: did some reading. The risk is surprisingly low. For a 45 year old a single whole body scan has a mortality risk of 0.08%, and if the same person had one annually thereafter till 75, its a 1.9% lifetime risk. David, Brennee and Ellison in Radiology, 2004.
