Actually, My X-Ray from last July revealed Pneumonia.
My doctor balked at it and ordered a CT scan.
Pulmonary Embolisms.
I still say a doc should be slow to order any X-ray! Your chances of cancer go up with every X-ray. You cannot rule out pneumonia without an X-ray, however. But if the doc strongly suspects pneumonia, he can go ahead and treat it without an X-ray. An embolism is an emergency condition. This was probably in an ER?
