Chest X Ray #1

A standard X-ray has the radiation dose equivalent to 1-2 days of background radiation. The beam is traversing mainly air-filled lungs and so doses are much lower than abdominal or other films

Posterior Anterior CXR: patient needs to be able to stand or sit up so difficult if ill. The chest presses on the film cartridge (well it's all digital now). Best diagnostic quality.

Lateral CXR - rarely done now as CT used for exact placement of lesions

AP chest - the film goes behind the patient who can lie back. Done when the patient is ill. There is cardiomegaly and often poor inspiration and the diagnostic quality is reduced. Useful looking for gross pathology

Bilateral hilar lymphadenopathy classed as Stage 1 sarcoidosis.
