Radiology is so important for chest physicians – every patient requires a chest x-ray, as we can learn so much from this simple investigation. Interpretation of the CXR is not simple – most radiologists will tell you that interpreting the CXR is the most difficult skill to master. But there are ways of approaching the CXR that help minimise the mistakes, and maximise the chance of making a useful interpretation.
