Nothing like the Daily Mail for raising an eyebrow:
The bizarre requests to use CT scanners, normally intended for four-legged animals, at the UK’s leading veterinary college in north London were revealed as hospitals face pressure to adapt beds and wards for an increasingly obese population.
[...]
The practice of referring patients to zoos is commonplace in America where obesity has reached epidemic levels.
Is there more systematic evidence or at least coming from non-tabloid sources on the common use of animal CT scanners for obese patients in the US? (I'm pretty sure that's what the newspaper meant by "America" because the US tops the obesity charts, although apparently Brazil and Mexico are not that far behind.)
A reason to doubt the newspaper statement is that simple supply and demand theory suggests that in a country with a high number of obese people equipment manufacturers would make suitable equipment. On the other hand, it's possible for demand to outstrip supply for any number of reasons, including a more rapid change in demand (rapid obesity increase).
