VHI, Quinn and hibernian issue doctors with guidance for when they will cover a GP/ Consultant to order an MRI.
You cannot have a "reassurance" or " just in case" MRI. there have to be specific queries or specific clinical findings.
For example, back pain alone is not a criteria for an MRI, but if there are signs on examination of a nerve being impinged, the MRI will be covered.
MS, possible brain tumours, brain aneurysms, bone tumours, deranged joints are all covered. Your GP should have a boolet with these criteria, or they can be clarified over the phone with VHI.
there is an interesting statitic ( not sure if true but is an example of the overuse of imaging), that Orange County has more MRI scanners that some small european countries.
