Having a skill in Radiology can give you good scopes but that certainly don't mean that Physiotherapist don't have any scope. From a broader perspective, if you go for Physiotherapy then there are also very good scopes in hospital set ups as well as private practice.

So there are demand of both the fields provided you must have genuine interest on the subject as well as you must acquire skill from it.
