“Can pneumonia be diagnosed with an X-ray?”

If there are sufficient respiratory symptoms including fever, cough, breathing more than 20- 25 breaths per minute, and chest pain, then yes, pneumonia is possible. The chest x-ray is confirmation because if it is normal, then pneumonia is unlikely. A routine chest x-ray is not necessary if the symptoms are mild. Also important is age, and whether there are any co-morbid conditions, including obesity, diabetes, and heart disease. Hope this helps. If the symptoms are getting worse, then medical help is necessary.
