"Chest x-ray review is a key competency for medical students, junior doctors and other allied health professionals. Using A, B, C, D, E, F is a helpful and systematic method for chest x-ray review where E refers to external (chest wall, base of neck and shoulder girdles) and F refers to expected foreign material such as medical devices, foreign bodies and surgical clips or unexpected items such as gossypibomas. It is not sufficient to report these with the word “stable”. Every foreign item must be identified and assessed to make sure the appearances are satisfactory."
