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.
