Are you saying you wouldn't do a CT or MRI if you saw something on the CXR
or you would do one only if you saw something? I agree CXR is probably
indicated whether or not there's anything that would show on the CT/ MRI,
but I'm not sure it would have much effect on resources. My reckoning is
that most chest physicians would go for the CXR first; most neurologists for
the MRI, and ultimately most doctors would do both.
